It's because I really want this to work, and you couldn't care less.
And because of this I couldn't do what I had to do to make it work.
And you just went on hurting me, however you could, laughing.
And I couldn't laugh, because this would be over.
And I couldn't smile, because you wouldn't let me laugh.
And I couldn't be happy, because you wouldn't let me smile.
And this didn't work because I wasn't happy.

I'm not afraid of being alone: I'd rather be alone than not be happy.
It's because I really wanted this to work, and you couldn't care less.
