Why are so few 'children's' games played by adults? I'm not referring to playing with kids but rather with other adults. I recall playing hide and seek with a large group of my friends when I was in my 20's. We played at night in a large park by my house. One friend climbed a tree, another hid in a garbage can. All I remember is we had a lot of fun and none of us was under the influence either. I am also thinking about two years ago when my girlfriend and I (in our 30s and 40s) played tag on a large playground with two kids we were watching. As adults we are in pretty good shape and had a heck of a lot of fun playing tag for over an hour. Why don't we play fun games as adults? Why are the games we play all so serious and organized? Why do we have to have kids involved to allow ourselves to play? What is a popular game that adults play and that's similar to a kid's game?
