I remember the first time I traveled to a large city when Bluetooth headphones had first become the rage.  I saw a man walking down the street arguing loudly with himself.  At first I thought he was “one of those”  but then I saw another person talking to themselves and another and another and I began to spot the phones in their ears.  It still is disconcerting to be standing next to someone who says “Hello?” and you are not supposed to respond.  Now a new set of technologies will add gesturing in the air and poking ourselves as a new set of social norms.  I’m not sure I’m ready…
