^When you are young, everything is a game, but it is very
   serious stuff. (that's why kids fly off the handle when play is
   interrupted suddenly). But when you are an adult, everything is
   oh, so important - yet you forget two important things: It's
   still all just a game, and we forget to have fun. Relationships,
   health, work, life - they're all games with rules - some we
   learn, most we make up as we go along.^
