This is just a little "When I was a boy..." reminiscence; no message, just a glimpse of life way back when.
Because we lived in semi isolation out in the country, my brother and I usually had to provide our own entertainment. We didn't have a gang of kids around to play with. We never thought about this, it was just the way it was. Sports and games were things we did at school. At home all play involved imagination even if it was playing an imaginary baseball game (at least I always won!) To this day, I seem more comfortable in solitude than most people I know.
