Since I was expecting my first child, I had attended natural
childbirth classes. One of my classmates was in the hospital in labour
at the same time I was. She quickly requested drugs to ease her pain,
while I gave birth aided only by my husband's coaching.

When the nurses rolled me out of the delivery room, I spotted a
chalkboard. Beside my classmate's name was an A-; next to mine was a B+.

"Look at that!" I complained to my husband. "She took all the drugs
they'd give her and made an A-. I did it naturally and only got a B+."

My patient husband rolled his eyes. "Honey," he said, "that's your blood type."
