Olive: Why were you unhappy?
Frank: I fell in love with someone...
[interrupted by Grandpa blowing his nose]
Frank: ...who didn't love me back.
Olive: Who?
Frank: One of my grad students. I was very much in love with him.
Olive: *Him*? You fell in love with a boy?
Frank: Very much so.
Olive: That's silly.
Frank: You're right it was silly. It was very silly
Grandpa: That's another word for it.
