In a country home that seldom had guests, the young son was eager to help his mother after his father appeared with two dinner guests from the office.

When the dinner was nearly over, the boy went to the kitchen and proudly carried in the first piece of apple pie, giving it to his father, who passed it to a guest. The boy came in with a second piece of pie and again watched his father give it to a guest.

This was too much for the boy, who said, "It's no use, Dad. The pieces are all the same size."
