As a child I was always mesmerized by rain droplets on the window of an automobile.  I’d try to count them, get bored, then finally make a game of seeing how many droplets a falling one could collect as it made it raced down the window to sudden death on the slippery asphalt.  As an adult I still find myself participating in the same game and often scold myself for indulging in such childish ventures till I realize perhaps its not so much a childish game that enthralls me as much as it is the nostalgia of  an innocence just out of an adult’s reach.
