A Piece of Pumpkin Pie?

Jolene was only 8 years old and lived with family in the country with her parents and brother.  Consequently they did not often have visitors from the city.  One day Jolene's mother said that father was bringing two guests home for Thanksgiving supper.

After they had enjoyed the turkey, Jolene went to the kitchen to help her mother, and proudly brought in the first piece of pumpkin pie and gave it to her father.  He then passed the plate to a guest.  When Jolene came in with the second piece and gave it to his father, he again gave it to a guest.

This was too much for Little Jolene, who blurted out, 'It's no use, Daddy. The pieces are all the same size.'
