The Fourth of July weekend was approaching, and Miss Pelham, the nursery school teacher, took the opportunity to tell her class about patriotism.

"We live in a great country," she announced. "One of the things we should be happy about is, in this country we are all free."

Trevor, who was a little boy in her class, came walking up to her from the back of the room. He stood with his hands on his hips and said loudly, "I'm not free. I'm four!"
