Why Mothers Cry ....

"Why are you crying?" he asked his mom.

"Because I'm a mother," she told him.
"I don't understand," he said.
His mom just hugged him and said, "You never will!"
Later the little boy asked his father why Mother
seemed to cry for no reason.
"All mothers cry for no reason," was all his dad could
say.
The little boy grew up and became a man, still
wondering why mothers cry. So he finally put in a call to G-d and
when G-d got on the phone the man said, "God, why do mothers
cry so easily."
G-d said, "You see son, when I made mothers
they had to be special. I made their shoulders strong enough to
carry the weight of the world, yet gentle enough to give
comfort. I gave them an
inner strength to endure childbirth and the rejection
that many times come from their children.
"I gave them a hardiness that allows them to keep
going when everyone else gives up, and to take care of their
families through sickness and fatigue without complaining.
"I gave them the sensitivity to love their children
under all circumstances, even when their child has hurt
them very badly.
This same sensitivity helps them to make a
child's boo-boo feel better and helps them share a teenager's
anxieties and fears.
"I gave them a tear to shed. It's theirs exclusively to
use whenever it's needed. It's their only weakness.
It's a tear for mankind.
