Do Right #6: Call If You Are Late

In this age of technology where we can text, call or e-mail anyone at almost anytime, do we seem to forget our social graces when it comes to contacting people when we are going to be late or are not going to show up somewhere? I hear this all the time from people showing apartments, selling things online or even with restaurant reservations. People will call to say they would like to come over at a certain time and then never show up. Really? We have no trouble calling someone for something we want, but when it comes to wasting someone else's time, we don't care. It only seems right that if someone else is waiting on you that you either let them know you have changed your mind or that you are running late. Wouldn't it be a much nicer world if all of us were a little more thoughtful of each other's time?
