Just wanted to say I agree with you. I'm not a compatible friend for everyone, but just because I have some issues doesn't mean that I'm incapable of good friendship. I've never had a close friend who was only ever positive of negative-- I don't think I've ever met someone I could classify as either. I love my friends, and because I love them I love to be there with them when things are good in their lives and when things are bad.

There's nothing wrong with being depressed, having a generally hard life, or just being cynical. Some people might prefer to be surrounded by happy people, and I don't see a problem with that, but that's not everyone, nor should it be.

For the record, I have walked away from relationships because the other person treated me poorly-- I just don't consider "not being happy/positive enough" to fall into that category.
