Yesterday my student came to my house for tuition, and after that he played Gunbound on my computer. He was checking out his dream avatar that could be bought with real life cash, and after some calculations, he discovered that he would need $80. He was tempted to buy it, but he was constrained by the fact that he didn't have much money. The following conversation went like this:

Me: Nah, $80 is too much, I think it's a waste of money.
Him: Not really, if I work, $80 would be like nothing. Hey, if you work, would you buy it?
Me: Nah, I still think it's a waste of money.
Him: Have you started working?
Me: Yah.
Him: Oh! At Mac's or what?
Me: No, I work as a tuition teacher.
Him: ....

I wonder if it is a good thing that I don't really seem like a tuition teacher to him.
