I wanted to just briefly serenade a particular kind of bitterness: it's the long walk on a hot day through blinding daylight along some pedestrian-unfriendly stretch of urban desert. You've been there: along the back end of a convention center parking lot on an off day; underneath the Bangkok elevated train; past the unfinished development site in Delhi with weeds growing through the boxy modern concrete houses; plodding from one car dealership to the next, 1/4 mile down the marginal commercial road with plenty of streetlights but no sidewalks.
You feel vaguely ill, inexplicably weary, despite little physical exertion today. You wonder how you could have ever jogged, sprinted, played a game. It is really far to the next thing. It is really hot. There are no other pedestrians around and the air smells like exhaust.
