Back in the day, there were no computers. The interwebby thing did not exist. Television was a dream in the minds of the vacuum tube inventors. Telephones, yes. They were bolted to the wall, or they stood on a desk looking like, well they defied description. The ringing of the phone was an event; and "wires" or telegrams were sure signs of tragic events in the lives of the senders. 89% of today's communications terminology had yet to be created. It may be 92%, but when one makes up statistics, accuracy is not guaranteed.

The stack of letters shown above were handwritten with a pen, delivered from one's place of residence to the home of the recipient by the United States Post Office. As you may note by the first-class stamp shown, the cost was three US cents. Mail delivery was effected Monday through Saturday, and it was brought to your door twice a day. I know. You are incredulous, unless you, too, can remember the day. Or unless you are so very young that you are thinking, "What do I care about the old poop and his day?"
