Confession: Excitement on the Subway

I greeted somebody I knew on the subway for the first time this morning.  Granted, I just met her last night; she led the class I took at the Y.  And we didn't formally introduce ourselves until this morning.  But still - I'm just standing there on the packed express A train, reading my book on the way to work in Manhattan, then I say a few words to another local.  It kind of made me feel like I live here - just a little bit.
