I have fallen asleep while playing a board game with my child.
One afternoon we were playing Guess Who on the living room floor. The sun was streaming in through the windows and I had propped a pillow under my head for...ahem...comfort. The next thing I know I'm hearing, faintly at first and then with growing intensity, "Mama! Mama! Mama! It's your turn! Mama! It's YOUR TURN! MAMA!!!"
I swear I snapped awake. I was that asleep. That's kind of a sucky thing to do to your child, right.
(It was kind of sucky that she woke me up from my nap too, right?)
