Left to their own devices, the kids will use their imagination. I guess at home they play computer games, but if they’re bored enough & have no set task and no “real” toys they will make stuff up the way I used to when I was a kid. I’d much rather see little boys chasing each other around with bookends (I work in a school library) pretending that they’re ray guns or something then see them sitting motionless in front of a computer screen playing a computer game — and I’d much rather see little girls getting giggly & loud, playing “school” than checking out each others’ nail tips!
