What's a friend...

I've been thinking lately...what is a friend. To say I've been burned by "friends" in the past I think would be an understatement. I'm sure we all have been used, treated badly, ignored, etc by someone we consider our friend. No matter how old I am (even at 30!!) it hurts and it sucks. It amazes me that as adults we can still be so ridiculous and hurtful.
Maybe it's me...maybe I don't communicate effectively, maybe my expectations are too much, maybe I'm needy, maybe I'm moody, maybe...I've had a thousand maybes going through my head lately.
I'm really missing my friends...these ones.
