Mr. Brown lived in a small town, but he worked in a big city. So he moved there with his wife
and two children last Tuesday.
On the next day, Mr. Brown took his new car out and was washing it. When a friend came, the
friend stopped and looked at the new car for a minute. Then Mr. Brown turned and saw him.
The friend said, "That's a new car. Is it yours?"
"Sometimes, "Mr. Brown answered.
The friend was surprised. "Sometimes?" he said, "What do you mean?
Mr. Brown answered slowly, "Well, when there's a party in town, my daughter, Jean drives it.
When there's a football game, it's my son Joe's turn. When I have washed it and it looks really nice
and clean, my wife Linda uses it. And when it needs cleaning, it's mine.
