A boy and his father were playing ball in the front yard when the boy saw a honeybee. He ran over and stomped it.
"Don't do that, that was a honeybee," his father said, "he wasn't doing anything to you. For killing him you will do without honey for a week."
Later the boy saw a butterfly, so he ran over and stomped on it.
"That was a butterfly," his father said, "he wasn't doing anything to you, and for killing him you will do without butter for a week."
