Speculation

Sarah: I wonder what I'm going to marry.

Me: Won't you marry a boy?

Sarah: I have to marry a boy who's a friend. . . a friend. . . a friend. . . Hey! Maybe I could marry Brandon (eight-year-old friend).

Me: Do you think so?

Sarah: Well, Sissy wants to marry Alex (Brandon's five-year-old brother), but he's too tough for that.

Me: Oh.

Sarah: Is Brandon too tough?

Me: I don't know.

Sarah: Well, if Sissy marries Alex, maybe I'll marry Brandon.
