And say you sit right next to the grouchy person in the back. We'll call her "Shelly".
Now, say you, Kevin, spend your entire day on the phone, making approximately 100 short, outbound calls, and receiving approximately 100 short, inbound calls.
And say every time you make a call, you dead-pan identify yourself like this:
You get the idea. No "Hey, how are you?" No, "Hello, my name is Kevin". No consideration of the fact that in our building(s), we have caller ID and, almost all of the people you are calling already know it's you...Kevin.
Additionally, say every time your phone rings, you pick it up and say, "It's Kevin". (Which I'm sure it's supposed to be "This is Kevin", but it ends up sounding like, "It's Kevin" or even "Tis Kevin", because...you are a fast talker, Kevin.)
Let's just pretend, for one moment, that this is you.
How ya doin', Kevin? Just heard a cool thing today, and thought you might be interested: Variety is the spice of life, hon. Oh yes! It's true! I hear that in other lands, people answer the phone by saying all kinds of different things! Sometimes, when they call people, they relay a bit of greeting to that person, just for the hell of it! Like, they may ask, "How's your mother?" or something that shows that they are at least vaguely interested in the other person, who, unfortunately, isn't "Kevin".
I know...it's crazy....that would never work. And besides, who has time?
