Andre's art teacher ...

  uses humor to correct mistakes.

Dan:

Andre, hi.

Andre:

Hey, how are you, Dan?

Dan:

I haven't seen you since you went off to art school. How do you like it?

Andre:

School is great. I have this drawing teacher, Mr. Parker, who is so cool.

Dan:

Oh, what do you like about him?

Andre:

Well, you know how I hate it when someone criticizes my work?

Dan:

Yeah.

Andre:

Well, this is the kind of teacher who is completely honest and direct without being egotistical or opinionated.

Dan:

So, he doesn't criticize you?

Andre:

Not really. And I don't mind it when people use humor to correct a mistake. It doesn't seem like criticism, then.

Dan:

He sounds great.
