25 Secrets People Accidentally Uncovered About Someone Else That They'll Never, Ever, Ever, Ever Tell Them They Know "No, I have not told her that I went through her phone and know about this." Reddit user CraftBeerCritic_ recently asked, "What's a secret you discovered about someone that you'll take to the grave instead of telling them you know?" People didn't exactly "take these secrets to the grave" because they did decide to share them with the internet, but I'm not complaining. Here are the wildest secrets people are (sort of) keeping: 1. "I found out that my mum had a one-night stand with a guy that I had also had a one-night stand with. I sure as hell won't be letting her know that one…" —Tea_no_sugar 2. "I was hanging out with a friend who had shown me a screenshot of a guy I liked asking her out. Later that day, I opened her iPad to play a game while she was on the other side of the room, and I saw that she had forged the message. I didn't want to embarrass her, and I figured she probably felt like we were in competition, so I kept my distance after that." —Fair-Cartoonist2671 3. "My former best friend told me they had cancer. After a few months, I was asking about treatment. They did radiation, but couldn't remember what dates they learned their diagnosis or began radiation. They told me not to discuss it with their parents. While I was using a DNA account of theirs to look up my own family information, a survey they completed popped up, and under 'Have you ever been diagnosed with or treated for cancer?' it said 'no.'" —Youdont0wnme 4. "My husband's brother is a top gay creator on OnlyFans. I'm also certain his wife would be livid if she found out, especially because he specializes in 'the boyfriend experience.' Since I'm not in the business of ruining marriages, I've told no one, including my husband or sister-in-law, but she’s a real 'c-u-next-Tuesday.'" —Longjumping_Time3031 5. "My first roommate, who was male, had Playboy pictures where he had pasted his mother's face over the faces of the models. I only found it when I looked in his desk drawer for the electric bill that he had neglected to pay. It was the event that made me change my major to psychology." —CoatGeneral5987 6. "My best friend has been with her husband for 10 years, married for three. Two years ago (one year into their marriage), I found out he had sex with a stripper while they were engaged. They now have a marriage, a beautiful baby girl, and loving, supportive families. I just can't bring myself to tear down her world like that. I can't ever tell her. It will shatter her. I have, however, told him that I know, and he's lucky I love his wife enough not to shatter her world." —rubabyy 7. "My relatives used to use me as their free IT person. My dad had me fix his computer, and long story short, he was catfishing other men online using pictures of his girlfriend's daughter to get men to send him money and gifts." —Mamamissy777 8. "I know why my one friend ended up in the hospital for a few days. It had nothing to do with his kidneys and a lot to do with a woman biting his dick." —sasksasquatch 9. "I found out that a very prudish family member and her husband have been playing with their friends: swinging. I'll never tell, but it makes me giggle every time I see them. She forgot about the cameras at my house. I asked her to keep an eye on my animals while I was on a weekend trip. They decided to use my house for a party. Thank goodness there are no cameras in the guest room. What happened in the living room was enough. She isn't acting weird, so I don't think she knows that I know. When she lectures me about my life, I just recall what I know. I may or may not tell, but probably won't. I'd like to keep this relationship." —ShirleyMF 10. "Long story short, I (a therapist) found out the owner of my group practice referred her daughter's girlfriend to me. Neither of them knows I know, and my client has shared with me far more family drama and secrets than I ever wanted to know about a boss, but that’s not my fault; they set it up this way." —ThriftFlipRepeat 11. "My very performative Christian father-in-law claimed to go on a mission trip. Turns out he actually went on a 'sex tourism' trip, and he even brought my mother-in-law back an STI. My husband's cousin found out and drunkenly told me. When I asked him why he'd tell me and not my husband, he said he didn't want to let him know his father is even more of a scumbag than we all already knew. It's eating me up inside, but I refuse to hurt my husband with that kind of information. I've told him his cousin told me something very upsetting about his parents and asked if he wants to know. He said he doesn't, so I won't say a word. To be clear, I'm only keeping the secret from my husband because I never want to hurt him. But if I'm ever in the same room as my FIL again, it's on sight!" —my_okay_throwaway 12. "My dad's best mate was sleeping with my mom when my parents were trying to fix their relationship. Both parents divorced. His best friend died in a motorcycle accident. No good can come from telling him." —Insertgeekname 13. "I went through my best friend's phone one night and found the conversation between her and her sugar daddy where she texted him while staying the night at my house. Sitting next to me, on my couch, she peed in a diaper. And she got off on the fact that she's doing this freakiness next to me, and I had no idea. There are a few more details I'll leave out, but that's the gist. It took me maybe a week to come to terms with and move on from it. No, I will not explain myself. No, I have not told her that I went through her phone and know about this." —WheresPerry-- 14. "I helped a lady in her mid-50s move into a smaller home. She was a recent widow of an acquaintance from a social organization I belong to. One of the boxes broke as I was loading it onto my truck. She had quite the collection of bondage gear. I would never have guessed from her demeanor and wouldn't dream of mentioning it to her. You never know what's going on in others' lives." —blubaldnuglee 15. "I learned that my grandfather had an affair almost 50 years ago. They just had their 70th anniversary. He is 98 now and is a little more out of it than he used to be. He was telling me a story, as he always does, but it ended up being about a completely different woman. I'll never tell my mom or grandmother. No reason to stir that pot at this point." —rabidgonk 16. "We bought a computer many years ago from my mom, and when we got it set up, there were emails left on it all about penis enlarging supplements. Order confirmation emails and angry review emails from her husband (at the time) complaining that his penis didn't get any bigger. It was wonderful because he was the guy she cheated on my dad with, lol." —anon_opotamus 17. "My grandparents didn't meet where they said they met; they connected instead via a 'Seeking Arrangement' type ad. Not that scandalous in the age of Hinge and Tinder, but pretty funny and would 100% not have been approved by the families back then. To my knowledge, I'm the only person who knows, as I found a letter in a safety deposit box after their passing." —laurenderson 18. "My cousin is actually my half-brother. My great-aunt told me before she passed away, but didn't want the cousin to know. Just to make it clear, my dad slept with his brother's wife. But hey, my mom also slept with my dad's brother. Dad knows, but Dad does not know that I know." —fishkybuns 19. "My mother got drunk and confessed that she had an abortion in her teens that led to a severe infection, rendering her infertile. She didn't remember her confession the next day. I'm adopted." —Effective-Report7750 20. "I used the family computer, only to find out my parents are swingers. I discovered what AdultFriendFinder was at the age of 16. I'm 29 now. That was quite the WTF moment." —J-the-Sparky 21. "My husband's friend is an alley cat and worse. He has slept his way through our entire friend group, including three of my closest friends (two of whom are sisters). I know about all of them, but they don't know about each other, and they don't know I know. Keeping it that way." —universechild9 22. "I was moving into a new house with two roommates, one of whom was related (cousins) to our new landlord. The landlord used this house as extra storage, so instead of a security deposit, we agreed to help clean out the house. As I was cleaning out the living room, I found a large DVD/CD case. Curious to see what movies were inside, I opened the case and to my surprise, out fell about 20 boudoir photos of our landlord... We quickly placed them in the back of a large photo frame and never spoke of it again. Lived there for six years." —PenisfullofInk 23. "I caught a relative eating their boogers once when I walked past their room. They had headphones on, so they didn't hear me pass by. I just acted like I didn't see shit. This was 20 years ago. No need to tell anyone." —TotoRabane 24. "I once overheard my parents arguing about my mom having a 'fuck buddy.' It was the plumber. We went to the same church, and his daughter was in my brother's class at school." —NemoHobbits 25. And: "I catfished someone, and apparently, it was so powerful they named their first child after it." —lucasmines Have you ever accidentally uncovered a secret about someone else that you'll never tell them you know?
