Melody: [reading from a tombstone] "Fifty years' happiness." How long's fifty years?
Daniel: A hundred and fifty school terms, not including holidays.
Melody: Will you love me that long?
Daniel: [nods affirmative] Mmm-hmmm.
Melody: I don't think you will.
Daniel: Of course. I've loved you a whole week already, haven't I?
