MrSteve called Friday morning for a chat, and ended up getting more than he bargained for (don't worry, he's used to it). Specifically, he got some (slightly) greater detail on my encounters with the stranger than I went into on the blog. Which really just confirmed what he'd already assumed, to wit:
"I kind of figured something happened because that's how you shake hands."
I resemble that remark a bit too much to be offended.
