A studious young fellow

Mom and Aaron are in the car on the way to his Kindergarten screening.

Aaron: I know they're going to ask me some hard questions.
Mom: Oh really! What do you think they're going to ask you?
Aaron: I know they're going to ask me how to say thank you in Chinese.
Mom: You really think they're going to ask you that.
Aaron: Yup, but I already know the asnwer. It's say say (more like shay shay with a long a, spelled tse tse in Pinyin).

This kid was prepared for the worst.
