Fireworks.

On the way back from Dave's, Ray and I stopped to watch fireworks go off.

Eventually, Ray said, "Mom, I'm bored and tired. I'm done with fireworks."

"Awww..."

"Mom."

So we went. But as we were driving, she announced all the fireworks she saw as "pinalleys," as in, "That was a beautiful pinalley!" Finally, about Castle Rock or so, there was a particularly good one that she did not announce.

That's how I knew she'd fallen asleep.
