Wow aquinas - that's something else. Good thing you are able to see it as experimentation!

My DS7 got the after-school staff all worried by his thought experiments with 'nothingness'. For several weeks he kept asking us (and others, I guess) what it would be like to feel nothing. Not just having your eyes closed, because then you would still see black and that wouldn't be nothing. I think the after-care staff thought he was depressed.

Actually, because he's not super talkative, and it's hard to know what's going on in his head, we were a bit worried as well. All we get are these (seemingly) random questions over a period of days, with no explanation.
