My daughter put me to sleep

I was relaxing in the recliner while my daughter was 'reading' to her babies. It was a quite calming, even though she reads very loud and is always telling one of the kids to sit down and pay attention. So, I drifted off. The next thing I know, it is very quiet. I open my eyes and my daughter is standing in front of me.

"Why are your eyes closed," she asked me.

I lied and said I was just resting my eyes. I told her to keep reading -- I wasn't ready to get up yet.
