An 8-year-old girl and her mother are walking along the street together one day. "Mommy," says the little girl, "how old are you?"

"Darling, you should never ask a woman what her age is." "Why not?" demands the child.

"Well, that's something you will understand one day when you're grown up."

"Mommy," asks the girl again, "how much do you weigh?"

"Never mind," answers her mother. "Why can't you tell me?"

"Because grown-ups never talk about how much they weigh. This is something you will learn someday."

"Mommy," insists the child, "can you tell me why you and Daddy got divorced?"

"Darling," responds the mother in exasperation, "that's something still very painful for Mommy, and I really just can't talk about it now."

A few days later, the child recounts this conversation to a friend at school. The friend explains how to overcome these problems:

"All you have to do is get your mother's driver's license. It has all the information about any grown-up you want on it. You just read it like a report card and it'll give you anything you need."

So the little girl does as her friend recommended.

Next day, she walks up to her mother and says, "I know how old you are! You're 35!"

The mother is very surprised.

"And I know how much you weigh. You weigh 136 pounds, right?"

Her mother is now shocked.

"AND I know why you and Daddy got divorced. You got an F in sex!"
