TO MY NEPHEW AND NIECE CLARENCE AND MAY ZEITLER
Your life, if you live it like the average boy, is split up into four parts and these are (1) eating, (2) sleeping, (3) working and (4) playing.
Now I haven’t a word to say about the first three phases of your existence for you will attend pretty well to the eating and sleeping ends, and your elders will quite likely see to it that you get enough work to do in and out of school.
But when it comes to playing I want to edge in, for this is a very important and often a sadly neglected part of your daily routine. There are three kinds of playing, namely (a) where your mind only is engaged as for instance at dominoes, checkers or chess, (b) where your body is chiefly in action as in gymnastics and outdoor games, and (c) where your mind and body are doing something more or less constructive.
