“I was a mean girl because I needed to survive high school. I had some really good friends when I was younger, but then in junior high, this girl started picking on me, but then wanted me in her group. I became part of her group so that I wouldn’t get picked on. She was a horrible friend who told everyone my secrets and just made me feel horrible because of things she made me do to my old friends.”
“I finally went to band camp in the summer before grade eight and made amazing friends that helped me get out of that old friend group. I found real friends who were loyal and kind to me, and I never looked back. I feel horrible about all the mean things I did, and when I see those I wronged, I try my best to apologize, although I do not blame them for still hating me.”
