When I was a kid, I had a female friend. I really liked her, but whenever we were together, I'd be quite horrible to her, insulting her etc. I couldn't think of any other way to joke around with her and I'm amazed she even talked to me for as long as she did. After a summer holiday, realising how horrible I acted around her, I avoided her, not even wanting to try being friends again out of fear that I'd go back to my horrible ways and make her life worse. ;_;
