Every summer in my neighborhood we’d have our own Olympics. We’d set the whole thing up and practice and then have the parent’s come and watch.
We’d fight all the time and then make up. Parents never got involved.
We played army, kill the guy with the ball, sandlot football (no pads), cow field baseball (with cows), and demolition derby (on sleds). We made gravity powered go-carts and tree forts, and we broke things on purpose and then tried to fix them. This was in the late 60’s/early 70’s, and we did all this without our parents’ direct supervision. (Most of the time we didn’t even have indirect supervision.) The world was no safer then, than now, and yet our parents allowed us to roam the neighborhood and beyond at will from sun-up to sun-down, as long as we were home for lunch at noon and dinner at 5:15 pm.
