Psychology Question

If no parents are there to hear them, do thirteen 4-8 year old girls make any noise?

I couldn't possibly answer that because I was there and I am a parent. But what I can tell you is that they make jet engines sound like a whisper. I know they had fun, but I've had less ear ringing after an 80's hair band concert.

It's now 9:00 and they are sitting quietly in front of movie. We're down to 10 - three didn't want to spend the night. Hopefully we're down to about 2 hours before they are all asleep. HAHAHAHAHAHHAHAHHAHAHHAHAHAHAHAHHAHAHAHA!!!!!!!!!!!!!!!!

The real question is - what possesses people to have children invite that many girls into their house?

Of course I'm just joking - it has been a blast - a very loud blast.
