What is friendship...?

Sometimes I feel like I'm not as good a friend and I don't have the same relationships that I see with others. Not that I should be comparing myself but I just read my friend Vicky's blog. She's so good about keeping up with people but I'm so good at losing touch with people. I'm going to find my volunteer opportunity and never get to talk to my friends, I'll make new friends and forget the old. How sad would that be? Sometimes I really feel like I suck at life.
