(Short story that can make you smile)

A curious child asked his mother:
“Mommy, why are some of your
hairs turning grey?”
The mother tried to use this
occasion to teach her child: “It is
because of you, dear. Every bad
action of yours will turn one of
my hairs grey!”
The child replied innocently:
“Now I know why grandmother
has no any black hairs on her head.”
