Confused by a line of a sitcom.
I'm watching a old sitcom called The Golden Girls, and there's a line I can't understand.
Rose:I can't sleep, either. Why don't I make us all some warm milk? After I drink milk, I go right to sleep.
Blanche:I can think of something else after which I go right to sleep. Huh, Dorothy?
Dorothy:During.
What do Blanche and Dorothy mean?
