If you're in a suburb what else is there to do? Going to any interesting spots to hang out with friends involve asking your parents to bring you there with the family car and then arranging a strict timetable on when to pick you up again.
i mean, i agree with you, theres nothing to do anymore. but surely there was less to do in the 50s? if youre poor, theres never much to do really.
I think just being able to get together with a couple other kids means that, even lacking videogames or boardgames or whatever, means that the opportunities available abound. Kids are infinitely creative and very good at inventing games out of any situation you throw them into. Give them two sticks and a piece of string and they'll turn it into a game of "don't let the string hit the ground" or something.
But, alone, yes I agree there was far less to do.
The fact that adults don't have third places anymore affects kids just as much, maybe even more.
