What I don't get--and this is only partly related to cell phones--is how many personal phone calls some people make and receive during the workday. When did it become the norm for everybody and their brother to chat throughout the day? Several people I work with spend half the day on the phone with their spouse, friends, children, etc. I very rarely make or receive personal calls during the day. It just seems like a lot of things can and should be discussed at home after work. To me, it's just another example of how self involved people have become.
