Seth: Why do people cry?
Maggie: What do you mean?
Seth: I mean, what happens physically?
Maggie: Well... umm... tear ducts operate on a normal basis to lubricate and protect the eye and when you have an emotion they overact and create tears.
Seth: Why? Why do they overact?
Maggie: [pause] I don't know.
Seth: Maybe... maybe emotion becomes so intense your body just can't contain it. Your mind and your feelings become too powerful, and your body weeps.
