A  mother is driving a little girl to her friend's house for a play  date.

"Mommy," the little girl asks, "how old are  you?"
"Honey, you are not supposed to ask a lady her  age,"
the mother replied.

"It's not polite."
"OK",  the little girl says, "How much do you weigh?"

"Now really,"  the mother says,
"those are personal questions and  are really  none of your business."
Undaunted, the little girl asks, "Why  did you and Daddy get a divorce?"
"That is enough questions,  young lady, honestly!"

The exasperated mother walks away as  the two friends begin to play.
"My Mom won't tell me anything  about her," the little girl says to her friend.

"Well," says  the friend, "all you need to do is look at her  drivers'
license  It is like a report card, it has everything on it."

Later  that night the little girl says to her mother,
"I know how  old  you are, you are 32."

The mother is surprised and  asks,
"How did you find that out?

"I also know that you  weigh 140 pounds."
The mother is past surprised and shocked  now.
"How in heaven's  name did you find that  out?"
"And," the little girl says triumphantly,
"I  know why you and  daddy got a divorce."

"Oh  really?" the mother asks. "Why?"
"Because you got an F in sex."
