I so thought you were going to say that you wished you were a kid again so that you could sit your fat *** around the house, eating twinkies and playing video games all day.
When I was a young kid I was a freakin' monkey. I would spend hours scouting out the good climbing trees, trying to get on to that damn first branch, and then seeing how high I could get. ("I can see my house from here!")
I would yell down to people and see if they could figure out where I was. Always had a blast. Sometimes, I would bring a couple water balloons. That never turned out well.
