A mother was driving a little girl to her friend's house for a play date.
"Mommy?" the little girl asked. "How old are you?"
"Honey, you are not supposed to ask a lady her age," the mother replied. "It's not polite.."
"Okay", the little girl said. "How much do you weigh?"
"Now really!" the mother said. "Those are personal questions and are none of your business."
Undaunted, the little girl asked, "Why did you and daddy get a divorce?"
"That's enough questions, young lady. Honestly!"
The exasperated mother walked away as the two friends began to play.
"My mom won't tell me anything about herself," the little girl said to her friend.
"Well," said the friend, "all you need to do is look at her driver's license. It's like a report card, it has everything on it."
Later that night the little girl said to her mother, "I know how old you are. You're 32."
The mother was surprised and asked, "How did you find that out?"
"I also know that you weigh 140 pounds."
The mother was past surprised. She was shocked.
"How in heaven's name did you find that out?"
"And," the little girl said triumphantly, "I know why you and daddy got a divorce!"
"Really?" the mother asked. "Why?"
"Because you got an F in sex."
