activities of daily living

Waiting for The Incredibles to start, a family in the row ahead of us was playing a guessing game. The kid was thinking of an animal and the parents were trying to figure it out systematically. "Is it an ungulate?" "Is it a quadruped?" "Is it a monotreme?"

When they finally gave up (it was an aardvark), the dad used his handheld computer to research the animal, probably to check his son's honesty.
