Girl: Why do you keep following me?
Boy: Because you're so pretty and I think I'm falling in love with you.
Girl: Really? But you haven't met my friend yet. She's prettier then me and she's right behind you.

Boy: Are you making fun of me? There's no one behind me.
Girl: No, but if you really loved me, you wouldn't even bother to look back
