Knowing Me, Knowing You

I generally think I'm a pretty good judge of character. True, I do look for the good in people and will give them the benefit of the doubt beyond when others will have given up on them. But that doesn't make me a naive person; I like to think I'm generally pretty aware of when people are using me and when they're genuine with me. Tonight though I'm not so sure. I'm not sure if it's selfishness, or cluelessness, or that they just don't care that much. If I've been used here, then... well I was going to put I hope karma gives them their just deserts, but the part of me that can't believe they were using me doesn't want anything bad to happen to them. I guess I hope that if they have used me, that they will stop doing so now, before I get more hurt.
