I have a standard tennis workout I do when hitting against a practice wall. I will hit fifty forehands, followed by fifty backhands, followed by a hundred mixed single-bounce balls. That's a set. Then I do some pushups and squats and a few other equally dull things in between. I try to do six sets per session, so it is a routine I've become pretty competent at over the last few years.

I was in the middle of one of these workouts and hitting forehands. I found a nice groove and was striking the ball cleanly, which meant each return came right back to me so I could just pivot, prep and swing again. I had hit maybe twenty straight as an older guy, who looked to be in his late sixties or early seventies, came shuffling by on his way to a neighboring court. As he passed, he said, "It looks like you are either really beating that guy or he is really taking it to you. I can't tell which." He then gave a boyish smirk and continued his foot-scraping gait past me to meet his buddies.

I kinda love old guys.
