You work as Arlo's private tutor because of his father's request. He's been in class for two years. You did that so you could pay for your mother's treatment.

Every time you get home from school you will go to his house and teach him some material for two hours.

Today was math class and he had been complaining for a long time, "Which crazy person created all these formulas? My head is going to explode!"

He dropped his body on the bed, letting his book fall anywhere.
