What are we?

Let me be your cannibal, I'll never be hungry. Let me be your friend, youll never be lonely. Let me be your coffee shop, you'll never be tired. What are we, what have we become? I'll try to be good, don't be mad because it's bad. You know I liked you alot, everybody said your a backstabber but it's too hard to let go. Keep me warm, with my own tears and blood. Are we OK? Why are we like this? Is this who we are?
