Talk To People You Like, Avoid Those You Don't

Lately, there have been a couple people in my life whom have gone out of their way to be cruel to me.  I don't really talk to them and I don't hang out with them.  To them I have a question: Why are you making me so important in your life? Why are you wasting your energy to try to put me down? It's just sad and pathetic.  It's not like I truly care, but it's rather irritating.  If you don't like me that's fine, just go somewhere else.  You are coming up to me, and I don't understand why.  Why are you bothering with someone you don't like?  Get over yourself.  It's not like trying to terrorize me is actually going to do you any good. Go get a life, and hang out with the people you do like, instead of following and insulting those you don't.
