I would respond with I have been better. Then I would ask her/him how they were feeling. Respond with one word answers and offer no information. ALways answer the question and immediately ask your boss the same question back. If questions get real unconfortable answer them with a story that has nothing to do with anything. Something like,
"That remineds me of the time when I was in high school and I tackled the running back in the end zone for a safety.......did you know there are only 2 or 3 safeties scored in the NFL in a year........I saw a game back in 1978 when Tommy Dorsett was tackled for a loss in the end zone and they didnt calll it a safety. That was the year the Cowboys lost to the Steelers when Swann caught the pass out of bonds and the refs called it a touch down. The Steelers won by 4 points because of that blown call........I cant believe Swann made the Hall of Fame he had terrible numbers.......... " ramble for a while then say, " Oh do you like football? If the answer is yes and it would have to be after u just rambled for 5 mins .....then say something like do you think the Panthers will win the super bowl?
Remember people love talking about themselves and their family. As soon as you can get your boss talking about her/his family you win your little conversation! Good Luck!
LOL, the football thing was very funny, thanks for the laugh, I will try that one
The other thing is, funny you would say that about "what are your hobbies" as I was asked that question during the recorded statement with the insurance company. My reply was "I walk" . I have not had any conversations with anyone I work with at all.
Facing my IME required by insurance company, any advice here as well. I have been warned it can be unpleasant and "anything you say can and will be held against you"
