Comes around

There was once a little girl who lived with her brother and her father. She had no mother. Her brother was not the nicest brother around, and would beat her up all the time. One day, the little girl complained to her father about it. The father soon had a guest house built on their mansion's lawns and moved into the guest house. He never set foot in his old house again.

Moral of the story:Aviation fuel has higher octane than regular unleaded gasoline.
