Morning sickness

The neighbor dropped in on a friend and found her sitting at the kitchen table, staring blankly at a half-empty cup of coffee, her three kids squabbling loudly in the other room.

"What's wrong ?" she asked.

The friend told her that she had "morning sickness".

Surprised the neighbor said, "I didn't even know you were pregnant."

"I'm not." the harried young woman replied. "I'm just sick of mornings."
