Caller ID said Univ of Utah but they congratulated me on my household being selected to receive something that would cut my power bills in half. Probably solar, probably not U of U, probably a computer calling. I asked if this was a recording and got the simple answer, "No." Most real people will give more than a one word answer. Even some computers are programmed to give a little laugh and ask why I think they are. Sometimes I stay on asking ridiculous questions that are unlikely to be in their database just to confirm my suspicions but this time I didn't want to further interrupt the book I was reading.
