Should I Facebook friend my high school bully?
I don’t suspect it really matters either way. It is really common to friend people who aren’t really your friends. However, you certainly have no obligation to friend her. One annoying thing I’ve discovered about various social sites is that people from your past will all of a sudden start bugging you. I personally find this bothersome, so I try to only friend actual friends and ignore everyone else. I would just ignore her.
