On Your Nerves

Seven months pregnant, my hand on my aching back, I stood in line at the
post office for what seemed an eternity.

"Honey," said a woman behind me, "I had back pain during my pregnancy. I
was bedridden for four months because my baby was sitting on a nerve."

The man in front of me piped up. . .

"You'd better get used to it now. Once those young ones get on your
nerves, they can stay there till they're 22."
