I don't want to miss the point about movement, but sneaking is a thrill, isn't it. I can see why children cannot resist the temptation!
Anything is better than video games....our 11 year old grandson doesn't even have to leave the house to visit. He just somehow tunes in his friends on his playstation thing and they all play the games together and can chat. In their own rooms, inside, basically alone🤔. Nobody goes nowhere these days. Even shopping is becoming keyboard oriented. Not good.
High school memories are something to accumulate and revisit. If you aren't on the move or don't move you aren't making good memories.....maybe?
