I like teeny-bopper/girlie girl shows (Sabrina, Hannah Montana, etc.) and movies (13 Going on 30, etc.).
I like to walk barefoot on a big piece of cardboard (Try it--kind of like popping packaging bubbles, which I also like to do).
I like to color (When little kids ask me to color with them they think I am so good at it--lol. I'm not artistic but kids think I am!).
I like to swing on playground swings. (I read an article once that said that a lot of people are putting adult sized swingsets in their back yards!).
When no one is around I like to make up silly songs and sing them. Also when no one is around I talk silly and sing silly songs to the dog and cats.
While I do read adult fare, I like to read kids' books now and then.
And for a food related silly thing, I sometimes eat pudding or yogurt by dipping my spoon quickly into the pudding or yogurt (holding the spoon vertically) so that it lasts a long time.
