Okay, here it is, your choice... it's simple, her or me, and I'm sure she is really great. But Derek, I love you, in a really, really big 'pretend to like your taste in music, let you eat the last piece of cheesecake, hold a radio over my head outside your window', unfortunate way that makes me hate you, love you. So pick me, choose me, love me.
In the end, it comes to this one simple choice, it's either me or anyone else. Like I said, maybe my sick, masochistic, selfish self is a bareer in the way of what should be. Maybe my fence is not keeping anyone out, maybe it's only holding me in.
But at that certain moment in time, when you realise all your hopes and dreams, and all you fears can't happen without him, and every song and movie and picture makes you imagine what he would think, then you are obsessed.
