Mr.Smith lived in a small town,but he worked in a big city. So he has to move to the city with his family.
One day Mr.Smith took his new car out and was washing it when his friend came. His friend said,"How beautiful the car is! It's new. Is it yours?"
Mr.Smith smiled,"Sometimes."
His friend was surprised,"Sometimes?"he said,"What do you mean?"
Mr.Smith answered very slowly."Well,when my daughter goes to a party in town, she'll drive it. When my son goes to watch the football match, it's his turn. When I make it clean,my wife will use it.So when it is dirty and needs to be cleaned, it's mine."
