-A guy had a crush on this girl.
He followed her wherever she went.
One day the girl asked the guy.
Girl: why do you keep on following me?
Boy: Because you're pretty and I think I'm falling inlove with you.
Girl: Really? But you have not met my friend yet. She's prettier than me and she's right behind you.
(The boy turns around)
Boy: Are you making fun of me? There's no one behind me.
Girl: No, but if you really love me, you would not bother to look back.
