Comcast called me yesterday for a customer satisfaction survey. I think they know via cable box that I have not connected my TV or watched any channels so they are calling me every two days to ask if I am happy. When I told her I was "satisfied, rating 5 on 5" she asked me: "Why are you satisfied?" That was a new one. I had to say "I am satisfied because I am not unsatisfied."
Opens up a Pandora's box of vexing philosophical issues.
Apparently this is not so uncommon.
