At what point does a kid stop laying on the floor and imagining what it would be like to walk on the ceiling? Or quit dashing back into the bedroom to see if toys secretly spring to life? Or stop practicing the crane technique like Daniel LaRusso from The Karate Kid?

And when did it seem normal to sit on the couch to watch television rather than…watch it upside down?

At some point…there is a last time for everything. But the joy and imagination should never be sidelined.
