Just call me the cab driver...or razorblade

That's how it feels. I'm like the person who comes into the life of another, in one way or another helps them from A to B, and then is gone. Perhaps it's my fault, I'm sure that is what a lot of other people would say if I hadn't. But I dunno, sometimes it seems like that's all I'm good for. I'm the friend who makes you feel better for awhile, gives you a shoulder to cry on when you need it, but isn't good enough for anymore. Or the girlfriend who is easily replacable by some hotter girl who has less opinion. That's the word...disposable. Once I get dull I get thrown in the trash. Of course there are exceptions I suppose. Those few few FEW people who, even if you don't talk regularly are pretty much ALWAYS there for you. But for the most part, every few years it's to the trash can for me. Where I proceed to start anew I suppose. And so I ask myself (and everyone reading this), is this something most people experience, or is it just me?
