We have become dependent on cell phones.  I remember a few years ago we were having a family reunion at a park somewhat equidistant from one sister and our house.  I remember my other sister expressing some reservations about meeting there:  she was concerned about getting cell phone reception there.  Almost everyone has a cell phone today and check it constantly.  Most people can’t conceive going anywhere with out.  In fact, others get somewhat nervous and anxious when they don’t have one with them or they are in a “‘dead” zone and have no reception.  All you have to do is go to a mall:  most of the teenagers have their cell phone glued to their ears as they walk around and shop afraid they will miss something.  I think it is downright impolite to be sitting at a restaurant and the person with you takes a call.
