W: Hi, Dr. Hyde.
M: So, what seems to be the problem today?
W: Well, I just came in for a check up and a dental cleaning.

M: Well, there is a major cavity in one of your wisdom teeth. Hasn’t this given you any trouble?

W: Uh, well, that sounds painful!
M: Don’t worry. I’ve done this... once before. Nah, just relax.

W: OK, well, whatever. Let’s get it over with.
M: Okay, pleasant dreams. Drill please.
