What is the meanest thing you've ever done?

[M.U.G.E.N]

two things

1. said something real mean to my brother...it literally hurts my heart thinking about it..I never got to say sorry and we are in GREAT terms with each other...but is one of the dumbest things I have done..to be fair I was just a kid then and acted on impulse..I make it up by being a great supportive brother to him

2. bunch of girls were bugging me in grade 11 or something at a tutoring class outside of school. I was getting annoyed since I couldn't pay attention to the teacher and waited till he left the room and turned around to say something back since they were right behind me and my friends. One of the loudest girls has a problem with her teeth..I'm not sure what the english term is for this but her teeth are just sticking out of her mouth a lot...for some reason she became the victim of my anger and I said something out rather loud to her which roughly translates to something like 'shut that trap of yours which is only good to be used in scraping coconuts'...it might be hard to understand this if you are not from my country but anywho the whole class laughed including her friends..I regretted right after but it was too late...she was bugged for a loong loong time..even after many years she gives me a glare that can freeze hell over lol..I truly regret it tho

great thread btw :)
