Go to the bathroom for some relief

You can't take this any longer; you need release. Raising your hand slowly, you get Patrick's attention. He walks quietly over to your desk. "Hey, what's up? What do you need?" he whispers to you.

Replying just as quietly you whisper, "I really need to use the bathroom. Can I leave for a few minutes?" He considers for a second. "Couldn't you have gone beforehand?"

You blush. "I guess I forgot, I'm just really stressed about this exam..." You try to put on a pleading face.
