One of the things I do in my class is pretty standard; hold up a flash card with the Chinese word for something, then ask a student to give me the English word. Fairly simple, right? So I hold up the flash card for 海滩, which is ‘beach’.
Me: What does this say in English?
Student: I know!!
Student: Ass. Crack.
Chinese teacher: *explains something to the student in hasty Chinese*
Student: Oh. Beach. 海滩 means ‘beach’.
Me: ….yes, good job.
