A quick word about Beneath the Surface by Dream Theater.
The song is beautiful first and foremost. Depressing but beautiful. But it also scares me. I don't want to experience what it describes, but I also have a horrible feeling that it will eventually, inevitably happen.
It'd be even worse if it also happened to the other person I'd be involved with. Not only am I scared for myself, but for them. I don't want to be abandoned, left in the dark shrugged aside like a mute. I hate to think that I'm capable of doing the same thing to someone else. That scares me.
