How does he know? HOW?!?!
How does a two-year-old son of admitted super geeks know that in a store filled with television screens of all sort of huge, fascinating sizes and content he's supposed to throw a tantrum when we take him away after 30 seconds from the tiny, little, travel DVD player screen that is showing Star Wars? HOW? HOW DOES HE KNOW?
It was a nasty tantrum too!
