What have I done...
I have been a bad friend to bad friends in the past. The person I was friends with (lets call them Person,) clamed I am immature, rude, and a few other things. She declared I needed to change, all because I had made a few mistakes. I told a friend about something we did, that she never told me I couldn't say, yet she found out and was angry "I don't want to brag," I told the same friend something else, something she also never said I couldn't say, and then lied about it because I knew she would chastise me. Once again she found out. But yet claiming I need to change is what I find rude, I have other friends who have not once told me I need to change, I even get along with one quite well, so clearly there is something about herself she also needs to change. I will admit that I was part of our fighting though.
So I suppose this is what I have done, hurt Person, and my x-friend. This is what will keep me from being friends with them ever again. Not like I want to be friends with them anyways.
