One day little Rivkah Stern was sitting and watching her mother do the dishes at the kitchen sink. She suddenly noticed that her mother has several strands of white hair sticking out. She looked at her mother and inquisitively asked, "Mommy, why are some of your hairs white?"
Her mother replied, "Well, every time that you do something wrong and make me cry or unhappy, one of my hairs turns white."
Little Rivkah thought about this revelation for a while and then said, "Mommy, what in the world did you do to Bubbie to make ALL of her hairs are white!?"
