Why did the man come back?

M: Mom, I’m back.
W: Did you buy all the things on the shopping list?
M: Well, not all. It’s a terrible time to do shopping. Big crowds everywhere, long lines at every counter. I’m tired of it.

M: The skirt is ＄10.00 and the shirt is ＄6.00.
W: Here’s a twenty-dollar bill.
