An elderly couple living apart

An elderly couple, living apart, had been dating
for several years. One day Elmer said to Betsy,
"We should stop this nonsense. We are paying two
rents, two car insurance payments, buying separate
food and cooking separate meals. We should just
move in together.

Betsy: Whose house would we live in?
Elmer: Mine, it is already paid for.
Betsy: Whose car would we keep and pay insurance on?
Elmer: Yours, it is newer and runs better than mine.
Betsy: Who would do the cooking?
Elmer: You cook and I'll do the dishes.
Betsy: What about sex?
Elmer: Infrequently.
Betsy: Is that one word or two?
