What Can Children Play?

It's true that in the past, children were happy playing with a few toys or they inventend them, but they could do a lot of things freely, now if they step on the grass, people can tell them to keep off it.
If they play a game and children climb a tree or hide somewhere or do something riski on the streets people tell them no to do.
If they play football people shout at them, because children can damage their cars. If children can't do anything freely outside, they have to stay at home, so its understandable that they need new games to play with at home.
