This afternoon Byron and I are enjoying the beautiful Chicago weather, taking advantage of the sidewalk seating at a local coffee shop. In case you were wondering, that looks something like this:

As we're sitting there a man in a wheelchair passes by, but he's in the kind of wheelchair that has handlebars that pump back and forth, pushing him along, in lieu of pushing the wheels to make the chair move forward.

"That's the best thing ever," Byron comments.

"Sure," I say, "except for the fact that the guy is in a wheelchair."
