Years back on my morning commute I would always see this older guy going riding the other way with no shirt on; every day, year round. He always had a big smile and a big wave for ~everyone~ he passed. The first few times I thought he was freshly off his meds or something. Mind you in Seattle riding shirtless in winter is doable, but nippy. Anyway this went on for a couple or so years so when I stopped seeing him I became concerned. I'd tell the story once in a while, and one day somebody tells me they knew his sister or something and it turns out he's just this guy who rode to work every day shirtless. He'd retired by then, but he still inspires me.
