Showing Confidence in His Cause

I have just received a phone call.
Upon my “hello?,“ a male voice began reciting "are you aware of the tea parties happening. . . "
Because it didn’t sound like a robo-call, I repeated my “hello,” and, sure enough, the voice faltered. When he caught himself and began again, I asked “is this a recording or a live call?,” because it seems pretty weird to phone someone, even a stranger, and read a script without adding any niceties such as “hello,“ “good afternoon,“ and so on. You know, humanizing elements.
Anyway, upon my question, he hung up.
