Light fare for a Sunday afternoon:
What's the protocol for identifying yourself when you call someone who you know has caller-ID?
When I was a child, I was taught to tell the person who answers the phone who you are, right away. “Hello. This is Barry Leiba, and I'd like to speak with Mr Biffelwogg.” Or, “Hi, it's Barry. How did the party go last week?” Even the nonsensical, “Hey, it's me,” serves the purpose, in the right circumstance.
But when I was a child, a telephone was a big, black thing with a dial full of holes on the front, your call was routed with mechanical relays, and no one ever imagined that you'd carry one in your pocket and know who every caller was before you answered. It's not uncommon, these days, to phone a friend and have him say, “Hi Barry, what's up?”, straight away.
But what if he doesn't? You call your bud's mobile, you know he's looked before he's answered, but he just says, “Hello.” Do you do the “Hey, it's Barry,” thing, assuming, of course, that your name is Barry? Is it now acceptable to just dive right into the meat of the call, at least with someone one's on familiar terms with, assuming that the initial ID has been taken care of? Or are we still supposed to pretend that technology is not our friend, and stick with the Emily Post recipe from days gone by?
I also note that before my time, the operator might have been listening in on your call, with the idea of picking up a tidbit or two of gossip. That won't happen now, but someone still might be listening in. Some things don't change much; technology just results in minor variations.
