I’m just as guilty of this as anyone I observe doing this. Checking your cell phone for messages when you exit the subway is almost exactly like obsessively checking your email during the course of the day. It’s fun to feel wanted and emails, voicemails and text messages are just one way in which you can indulge in that feeling. Someone should videotape people exiting the subway and immediately checking their cell phone, or calling someone before they go into the subway.

This reminds me of the shot from “Shaun of the Dead” which I thought was brilliant, in which they have the montage of how normal people can be like zombies in their everyday life. Specifically, the shot of the people at the bus stop simultaneously taking their cell phones out of their pockets to check what time it is. I love attention to details like that.
