Ok VCR. But DVRs are very common these days. My mom is about the only person that I know who doesn't have one...she still uses a VCR.
I don't know any 9 year olds that are up doing school work at 10pm? What do they do between 3 and 10 pm?

I have a nearly 9 year old.
At 11 I can see on occasion and non school nights but 10pm regularly?
What time do they get up for school??? I can't imagine that if they are regularly staying up past 10 pm that they are getting enough rest when most kids have to be up by 7:30 at the latest. It is recommended that kids that age get 10-11 hours of sleep a night.
Did your grandkids watch the AMA's? A broadcast that was rated TV 14.
