What's the worst thing you've done to a friend?

Well yes, I have.
But it's only because she deserved it.

I know i have but i can't think of any

I never did any thing major but I remember in 1st grade when me and my classmates were out to recess a few of my friends asked me to spin them on a big tire so I spin them around and the campana rang so we had to go back in the school and one of the kids that was the last to get off the tire, threw up and I felt bad for him.

Um... I admitted that I didn't want her to go out with the guy she liked because he is my ex and I still like him, even though I know he likes her and she likes him.

I also used a toothbrush belonging to another friend to pescado my collar out of a French drain, but that's más of a gross thing than a bad thing.

I slapped her. She was being bitchy.

i have not done anything bad to my friends
