Hi, dont hide any one the details, this is your time to express what the worst thing you have done is and no one is here to judge. To make you feel comfortable i will tell you mine - I almost killed my freind once, his name was jack and i threw a small rock at the back of his head. He got knocked out and a car ran over his leg. He had no memory of the incident and 4 years have passed and i will never tell him. XD
When I used to play baseball this guy made fun of my friend for having a lisp so in the middle of the game when I was pitching and he was batting I aimed for his head and broke his nose.
