Confused..

This saturday I attended a Hamfest in Wichita, Ks.. I tried to make some new friends out of Christians but they were not at all friendly. One of them spoke at me as if he hated me and I have no idea why. I have never met these people before. This is the kind of treatment that I get all to often and I don't understand why. Is it me? What is it about me that causes such hate in people? This is why I don't very often make an effort to ger new friends.
