When is the last time you had a good laugh like this?
Chances are it doesn't happen often enough. Kids have a real ability to be genuine. There is something to be said about 'keeping it simple'.
It may not have been a sheet of paper, but I remember some of my favorite toys ended up being the cardboard box.
My kids (4 and 7) have a Wii, iPods, too many cars and dolls, but still their favorite toys end up being some paper, brush and paint. The reason is simple, we just forget what it is.
