Can vampires cry in The Twilight Saga?

No, the vampires cannot cry, because they are DEAD! They are the walking, living dead. That's also why they can't blush, they are dead so they have no blood.

EDIT: This would be WRONG... Being dead doesn't mean you have no blood. It means your heart doesn't pump your blood. And I'm not sure the 'vampires' in Twilight can be called Vampires.
