I'll occasionally be riding my bike into the city or sitting on the train, and I'll suffer the tiniest fraction of a second of panic that I forgot to put on shoes. This happens most often after I've had a couple beers at home before heading out to meet some friends that night. It's such a quick feeling that there's no logic involved in it; it's logic-less, it's a simple feeling rather than a thought. Immediately after that tiny fraction of a split second, my thoughts turn to a new notion that lasts slightly longer but is still only a split second. This is the thought that I accidentally put on mismatched shoes. This feeling used to occur much more regularly when I would have to wake up at ungodly hours in the morning. To date, whenever I've looked down to settle my mind, I've found matching shoes on my feet.
