If you had a gymnastics mat, would you have thought to push all of the furniture out of the way, the coffee table against the wall, balance the mat up against the table, and then create a running/leaping/jumping circuit over the top and around again?  No, we wouldn’t have, because adults don’t think in these terms. These kinds of kakamamey stunts are confined to childhood, thank God.  It reminds me of the time my cousins and I went to the circus and decided to create our own tightrope between 2 trees.  There is a reason the Hillsboro, Illinois ER docs knew us by name.  Ah, the wonderful things we did before we had a sense of our own mortality.
