Most people are desensitized to the unofficial American greeting. "Who are you and what do you do?" is just a social nicety we expect.
We're even programmed to answer with short, clear phrases:
"I'm Jodi, home health care nurse."
"Katherine, divorced mom of one."
"It's Emily, blogger and church volunteer."
These post-comma words give us a feeling of security. They let us categorize an identity quickly and easily: "This is me in a nutshell."
But our short answers are never the whole story, are they?
