When I was young I was the kid in the cardboard box that was playing space station one minute and then Robin Crusoe the next. So long as I was allowed to use my imagination I was going to have fun. Playing with little kids was always easy for me then, it isn't hard to convince a 3 year old a cardboard box is really a race car... since then my imagination has dwindled and it has become increasingly harder for me to play with little kids, it is one of the seriously sad things about growing up: loss of childhood imagination.
It was for that reason that I found this all the more impressive:
I don't know many 17 year olds guys that are content spending over an hour playing with kids under the age of 5, when not paid. It made me in awe to watch my nephew playing with his very young nephews and actually have fun, and doing it without being asked.
