I'm not sure about you, but I play every day. Every. Day. And use my imagination on the daily when I paint, draw, doodle. So, I would say...no, we don't grow out of it. I think people do suppress it though, because they're "supposed" to. You know.... that's one of the things people say most about me..other than that I'm a hippie... is that I'm immature because I play every day. Bunch of weirdos if you ask me. Love you, Dr T! *mwah!
