My best friend

There is a message board I frequent where currently people are posting other peoples blog address/posts to see where they have talked about others. I just don't get it.

Speaking of that message board, someone on there hurt my feelings a couple of days ago. I thought about replying to her public post, but I didn't want to go the low way. I thought about emailing her about it, but I didn't want to make a big deal out of ot. Well, its 3 days later and its still bothering me. Why do I let people rent space in my head?
