When such is the case, it is easy to feel that life is about working hard and forget the adage that ‘all work and no play makes Jack a dull boy’. I came across this quotation from C.S. Lewis recently: ‘It is only in our “hours-off”, only in our moments of permitted festivity, that we find an analogy. Dance and game are frivolous, unimportant down here; for “down here” is not their natural place. Here, they are a moment’s rest from the life we are placed here to live. But in this world everything is upside down. That which, if it could be prolonged here, would be a truancy, is likest that which in a better country is the End of ends. Joy is the serious business of heaven’.
