It was summer 2009 in Valencia, Spain. The classroom was cool, the students tanned with glistening skin, the sparkle of youth in our eyes. We were eager to learn, and eager to play. One warm night it was tapas and dancing in the old town, gliding through the cobbled streets, surrounded by churches and buildings with a history. The other night it was fooling around at the beach, grabbing a few beers to while the evening away on the golden sand, chilling and laughing and acknowledging the breaking sound of the waves as they touched and tickled our naked feet.
