It's Thursday at 6:00 P.M. You go to Jade's mom's house to teach him math. You ring the bell, and his mom opens the door for you. She greets you and points towards the kitchen, as if you didn’t already know where it was. You head to the kitchen, where Jade is sitting, straightening his math book and notebook. He greets you with a short phrase

"...Hi."

He pauses, then looks down at his notebook.

"Today I want to study trigonometry."
