I have a hobby—well, not so much a hobby as a habit. When I meet people, I punch them in the solar plexus. Well, again, “punch” isn’t the right word. Most times, it’s a just a light tap, a brush that passes quickly. Other times, if circumstances permit and the mood of the moment seems just right, I really haul off and punch. It’s my way of getting to know people, a little signature touch to assure that both I and my newfound acquaintance remember the moment.
