It doesn't really bother me anymore if someone doesn't like me, but that's only been in the past few years. Before that I thought I'd done something wrong if they didn't. I think part of it's age and part of it's the knowledge that not all personalities get along. That doesn't mean their a bad person or I am, it just means our personalities don't work together. I work with someone now who I don't like nor does she like me. We work together so we'll discuss work related issues, but I wouldn't sit down and discuss how our weekend was, etc.
