Is this the state of the world now then CiG (lol). Reminds me of the advert that was on TV some time ago about mobile fones & txting, & the couple sat across from each other at a cafe table, and one txting to the other 'pass me the ketchup please'.
Nothing really new. I remember about 35 years ago, my sister sitting on the phone - when they used to be on a little table in the hall - and chatting to her mate across the road. They both had the front doors open and were waving to each other.
We email around the office all the time as it is a good way to get something across to everyone quickly, where I always feel uncorfotable is when I need to contact one of my collegues a few seats away and my supervisor will say give them a call, no they are only a few seconds away, phoning someone so close makes me feel stupid.
