Little Dewey and his family were having Sunday dinner at his grandmother's house. Everyone was seated around the table as the food was being served. When Little Dewey received his plate, he started eating right away.
"Dewey! Please wait until we say our prayer," said his mother.
"I don't need to," the boy replied.
"Of course, you do." his mother insisted through gritted teeth. "We always say a prayer before eating at our house."
"That's at our house," Dewey explained. "But this is Grandma's house and she knows how to cook."
