Did I ever tell you about how I used to bully a girl when I was in primary school?
I hope you've grown up since then.
I was jealous of her for being more grown up than me at the time.
Well, maybe you should try reaching out and apologizing for your behavior?  Sometimes people carry bad memories of bullying throughout their lives and it might help them you reached out and told them you're sorry.
Apologizing would be an easy way out of the hat I put on my head. I'm not a pussy.
Admitting you were wrong takes more guts than living in denial. If you really want to demonstrate your strength, admit you're wrong and help someone heal from the harm you inflicted upon her.
