"My friend and I went for a bike ride to the next town over when I was 13. I was pretty young to do it on my own, but he was 16, and I trusted him. We stopped at a gas station so I could use the washroom.
I come out to see that he bent my chain to the side, urinated on my bike, and had left me there. An hour and a half long bike ride away from home, without a bike or money or pride." -Reddit user kaboose286
"Spread a rumor that I was gay...
then it backfired, and everyone thought that he was gay with me." -Reddit user (deleted)
"I was 12 and eating lunch at school. Not popular at all, but I managed. Saw my only close friend having to eat on his own because our table was full, so I got up to join him and sit with him.
He simply stood up and sat in the seat I had just left. I lost contact with him, but I will never forget feeling so shut down in my entire life; it changed how I interact with people for the worse." -Reddit user alioriginal
"He made a "your mom" joke 2 months after my mom died, and I punched him in the shoulder for it. Admittedly, he warned me it would happen eventually, and I warned him I'd punch him for it.
He agreed that was acceptable. 20+ years of friendship, and that's the worst thing he's ever done." -Reddit user tyme
"Spent three hours listing everything she and her parents had decided was "wrong with me." I was 9. I kept myself from crying the whole time until I finally cut out and ran home, where I cried in my closet until I fell asleep.
I still considered her one of my best friends for years after because I had-have- trouble making friends, and she lived down the street. It still rides on me every once in a while." -Reddit user FormaldehydePeaches
"Is currently dating a man who took serious advantage of me while I was unconscious. Even though I hate him and refuse to be in the same room as him, and she knows what he did.
She acts like it was my fault. I need new friends." -Reddit user Jdhlove
"I helped someone who I thought was my close friend of many years set up for a barbecue party. This person was my next-door neighbor.
I cleaned the patio, helped with the shopping and food prep, etc., only to be told that I was not invited to the party as it was only for people who had done favors for her. I am no longer her friend." -Reddit user (deleted)
"Slipped vodka into my milkshake. He knows that my parents are alcoholics and that I never want to drink.
He doesn't understand why it hurt me so bad." -Reddit user (deleted)
"I really liked this girl, and this girl really liked me. The problem was I didn't know that she really liked me, and I was too stupid/shy/scared to try anything. My friend's girlfriend talked to the girl, though, and found out she had mutual feelings.
The girlfriend told my friend, but my friend never told me. I didn't get with her...Still think about it sometimes to this day." -Reddit user Avonescence
"Showed him a stuffed bear my aunt had given to me shortly before dying of brain cancer.
We were close, and she signed the tag on its ear, "Love aunt," then her name. He took a marker and scribbled over her signature." -Reddit user Smsmaho2
"He went out with the girl I liked.
And he knew I liked her." -Reddit user SwagMasterMo
"She basically told me that if I wouldn't give her my credit card details, we wouldn't be best friends anymore.
I guess we're not friends anymore then." -Reddit user ImNotAKompjoetr
"When I was fifteen my best friend got mad at me for something petty and started a rumor that I was pregnant." -Reddit user llama_laughter
"Pretty tame, I guess, but he essentially stopped being my best friend when he started dating a mutual friend, and it suddenly became all about her.
He also owes me like $700." -Reddit user Sparticus2
"I took the blame for her revenge scheme and got suspended.
She just convinced the entire school that I'm a psychopath while I was gone." -Reddit user neinhacker
