I’m in the middle of an 11-hour flight from Germany to San Francisco, squeezed into the middle of the very last row with sleeping passengers on both sides of me spilling over the armrests. My legs have begun cramping. Needless to say, I am not feeling very playful. But I’ve just started reading Bernie De Koven’s book A Playful Path and quite in spite of my cramped circumstances, I start to relax. My grumpiness starts to melt and a little fizz of delight begins tickling in my chest.
