Someone well stated recently that we are spoiled today with instant responses. When I was a kid like in high school, e-Mail was just surfacing but hardly anyone had it because technology wasn't there yet. We still used pay phones. We wrote letters and talked mostly in person. Computers were just coming out such as the 286 PC, Tandy PCs, etc. A text message was words in a book or a typed or handwritten note. Smart watches like you saw via a communicator watch that Dick Tracy had were things of fiction but now they are a reality.
The sum is that the older I get, and as someone who is an active communicator via many of the current means of communicating, I realize daily that realistic expectations need to be set for ourselves and others when it comes to response times. This however, doesn't give us a license to be rude and never respond or take weeks to respond because there should be a sense of urgency toward those around us...it just doesn't mean it has to be instant.
Something for all of us to reflect on...
