emotion

" - Why do people cry?
- What do you mean?
- I mean... what happens physically?
- Well... umm... tear ducts operate on a normal basis to lubricate and protect the eye and when you have an emotion they overreact and create tears.
- Why? Why do they overreact?
- I don't know.
- 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."
