I did many childish things in my life, things that were not "age appropriate", like playing with model trains, watching cartoons (I like Disney, for example), listening to music that I liked when I was a little kid which was specifically made for them. Sometimes I enjoy showing some childish behavior, manners and attitudes. Usually I get accused of it, but manage to get away with it...
I love to play with the sons of my cousin and the son of my sister's girlfriend. I do it as if I was a kid, too. I'm glad I'm not that awkward with them how I used to be.
