Think Before You Lie

One day a little girl was sitting and watching her mother do the dishes at the kitchen sink. She suddenly noticed that her mother had several strands of white hair sticking out in contrast on her brunette head.

She looked at her mother and inquisitively asked, "Why are some of your hair white, Mom?"

Her mother replied, "Well, every time that you do something wrong and make me cry or unhappy, one of my hair turns white."
The little girl thought about this revelation for a while and then said, "Then why are ALL of grandma's hair white?"
