I agree about how emotional clingy friends can be a little ... too much sometimes, well, I sure cant stand them if the indecision and dependence gets too overwhelming. And sometimes I think they are a bit selfish in doing that. But I have some friends who help these people whole heartedly and I think they are really kool.
Another thing: personally, I would rather not be friends with some people if they take me as a pity friend or something like that. because not only does it SOUND pathetic, it FEELS pathetic too.
