Event - In high school, I used to sit next to one of the most unpopular girls in school. I know she was trying to be nice to me by giving me gum every day, and I just couldn't resist returning the favor at least once ... only I gave her laxative gum.
Apology - I'm sorry I was so mean. You never deserved all the awful things people said and did. I promise I've changed over the past 25 years, and what I did to you has haunted me. I've looked for you, and if I ever find you on Facebook, I'll apologize directly to you.
Event - When I was in middle school, I left several vicious, anonymous messages on a classmate's LiveJournal to impress my friends. I called her pathetic and stupid and fake. She is a wonderful person and we became friendly acquaintances in high school. I never told her what I did.
Apology - You did nothing to deserve that abuse. I took out my own self-consciousness on you, and lashed out in the most cowardly way possible. I sincerely hope that you were strong enough to shake off those messages and not let them damage your self-esteem. I'm so sorry.
Event - All through school there was this one girl I didn't get along with. She was mean to me, and because I thought she was a bully I was mean back. I found out that she was telling people I was bullying her, and I was angry because I thought she was lying (SHE was the bully, right?) I said spiteful things about her behind her back, and tried to avoid her. We haven't spoken in years and I realise when I look back on it that she was very unhappy. I'm worried I made it worse.
Apology - I'm so sorry, I thought you were just mean and it never occurred to me that you might be having troubles too. I wish I could take back every nasty look and cruel word. I found you on Facebook but I'm too scared to get in touch - what if you don't remember me? Even worse, what if you DO?
