Get help with your homework.

"All right, let's do the homework," you say.

"Sensible choice," Mrs. Donovan says.

Mrs. Donovan begins with first principles and you finally begin to understand the unit circle and what trigonometry actually means. You do end up feeling quite stupid and embarrassed though before you finally get it. After some time, she says, "All right, Parker. You seem to be getting the hang of it. Make sure to finish this up and hand it in to me tomorrow. And don't forget to do today's homework too."

You thank her and head out.
