Why I make one hell of a tutor

Today.
Me shouting at kid.

K, who moves his tuition bag to the front of class says solemnly, "Teacher. I feel sorry for you."

My mind whirls. Eh?

K continues on earnestly, "Because you keep having to scold N."

Am I being pitied? By my student?

In a better frame of mind, I might have asked him why he didn't feel sorry for N instead, who was after all, the one being scolded.
