My Band Teacher...
Me: *raises hand*
Teacher: What?
Me: Can I go to the bathroom?
Teacher: I don't know, can you?
Me: MAY I go to the bathroom?
Teacher: Sure. Maybe sometime next week.
Me: May I go to the bathroom RIGHT NOW?
Teacher: Eww, no. That's gross. I would have to call the janitor to clean up.
Me: In a few moments can I go down the hall, into the bathroom, and PEE?
Teacher: I don't know.. Can you?
