Leaving so soon?

You must think I'm a fool, so prosaic and awkward and all. Do you think you've got me down? Do you think I've never been out of this town? Do I seem too eager to please to you now? You don't know me at all. I can't turn it on, turn off like you now: I'm not like you. Now that you're here, I bet you're wishing you could disappear. I'm trying to be kind, I get the feeling you're just killing time. You look down on me, don't you look down on me now. You don't know me at all! A slap in the face, in the face for you now. Just might do now. You're leaving so soon? Never had a chance to bloom, but you were so quick to change your tune. Don't look back If I'm a weight around your neck, cause if you don't need me, I don't need you.
