I was thinking about this earlier....
What has happened to these people that they have the need to constantly communicate...?
We didn't use to did we...?
I remember when I first went 'out on the road' selling stuff my 'communications device' was a pile of 10p pieces and you found a working phone box when you could and called the office (at least once a day)... Beyond that you wouldn't speak to anybody on the phone until you got home in the evening and used the land-line there...
What is so important now that you have to have a conversation in the supermarket...?
