To wit: (1) "Call Waiting" One is engaged in conversation with another on the telephone. In the middle of said conversation, one of the parties interrupts, saying, "Would you wait a minute, I have another call coming in", and then often, without waiting for a reply, the line goes dead. How arrogant. How impolite. My usual modus operandi is to either reply, "Only if that call is more important than this one", or, if not given the chance to reply, I simply hang up.
(2) The cell phone. Marvelous invention, no doubt. Instant communication, anywhere, anytime. And therein lies the problem. The ubiquitous cell phone is used anywhere, anytime. In stores and malls. In restaurants. In public restrooms. In doctors' offices, even in the exam rooms during the care of patients. Their annoying rings, often meant to mimic some great musical composition, are often heard in church services and funerals. Their use is often intrusive upon other individuals within earshot. And, with the volume of some such conversations, earshot can be quite a distance. Furthermore, the content of these conversations, which should be private matters, are often offensive and profane in content. Cell phone users seem oblivious to their immediate environment and their encroachment upon other persons' space.
Oh for the days of BUtterfield 8 and CRestview 6, phone booths, and home phones without all the bells and whistles. A more simple time, for sure. But a more civil time too, as far as phone etiquette is concerned.
