When I was still young enough to take naps (but not old enough to enjoy them), I would try anything to get out of sleeping, but my Mom always knew when I was faking. I asked her how she always knew, and she told me that when a person was really asleep, they stopped breathing. I could never hold my breath long enough to fake another nap again.
