When I was very young a new Junior High was built near our house. For some reason, it came with two tennis courts. Nobody in our area knew how to play, so they were always available.
Years later a friend and I decided to play all summer. We logged about 100 hours, which we thought was alot. We weren't very good, but at last we could sustain rallies, (and we learned that rallies weren't called "volleys").
Nowadays I don't compete seriously, but I'm glad I learned to play so that I can get exercise doing something more fun that the treadmill.
I strive not to laugh at human actions, not to weep at them or to hate them, but to understand them. - Spinoza
