These days, “calling” someone usually means pulling out a cell phone from a pocket or purse, rapidly typing a message in abbreviated “text” format using nothing more than two thumbs, or talking “face to face” or better said “screen to screen” via Face Time.

There was an era, though, when “calling” on someone meant stopping by his or her home for a visit. If you watch “Masterpiece Theater,” or were around in the early 20th century, you know that formal “callings” required knocking on the door and dropping an engraved card into a dish, which was then transported, via the “help,” to the home’s resident while the caller waited patiently to see if he or she would be invited in for a visit. This practice was for the idle and the rich; working people had no time for such frivolities.
