Living in the city can be odd sometimes.  There are a few people whom I regularly see in or near the 14th Street subway station because we commute at the same time every day.  (In most cases, they’re getting on the train when I’m getting off, or vice versa.)  They’re complete strangers, but I’ve been seeing some of these people every few days for years.  This morning I saw one such person walking into the train station wearing a neck brace.  For a split second, I almost went up to him and said, “Ohmygod, what happened?!?!”  And then I realized: Oh right…I don’t know this person.
