Ever since I've moved to this town, I've noticed that virtually all except those I've conveyed the following sentiment to who call me on the phone employ the most miserable phone etiquette I've encountered in the many states and provinces I'ved lived in.
When I was a child, I lived on the Upper West Side in a communal situation that had three women (including my mother) under 30. It being NYC and Ma Bell being the only game in town, it was standard practice for women to only give their first initial and last name when listed in the phone book.
In every other place in the land, when I received an unsolicited call (and especially when it was in fact solicited), it is common practice to announce (i) who is calling, (ii) who they are representing (if applicable), (iii) the nature of the call, and then ask if that person is available. Typically, the receiver--if the intended recipient--would respond with "speaking" or "this is s/he". You learn this if you ever worked in a phone bank or was an assistant to a major publishing house (Oxford University Press a lifetime ago). The recipient is placed at ease, knowing who they're talking to, and everything should go as swimmingly as possible after that.
From Town Hall to the hospital to just about everyone in this state, the first thing out of someone's mouth is "Is this Holland Mills"? (This came up today, but having realized I published my number on this site twice, I simply asked who was calling before self-identifying.) However--especially if the tone is hostile, as was the case a year ago with the wife a Very Special Member of the Selectboard called--I typically retort quite bruisingly that the caller needs to learn phone etiquette. I may or may not hang up depending on my mood.
I do not understand the mentality of someone calling a number and demanding information up front without giving some first. It's at best self-centered behavior.
(I admit there are a small number of exceptions; I ordered a supplement from a women's health center, and had something of a stand-off as the nature of their business can be quite sensitive so they want to know they're speaking to the person involved. I can't think of another exception.)
Please, if you recognize this behavior in yourself, kindly fix it.
Thanks for reading.
