I had a co-worker once (my superior in name only

) who would ask me to repeat myself every time he asked me a question. A typical exchange would be:
him: What did you find at the southeast corner?
me: A #4 rebar with a Baughman cap
him: What?
He wasn't hard of hearing, and I'm not soft-spoken. I got to the point where I was automatically repeating myself, and the conversations went like this:
him: What did you find at the southeast corner?
me: A #4 rebar with a Baughman cap
me: A #4 rebar with a Baughman cap
him: What?
I got tired of it, and one day flat out told him that unless he was willing to listen to my answer, there was no reason to ask me the question, and I was through repeating myself. He threatened to tell the real boss about my insubordination, and I told him to go ahead. Thereafter, the conversation went:
him: What did you find at the southeast corner?
me: A #4 rebar with a Baughman cap
him: Thank you
All of which is a long way of saying I've been there,
nlmcp. If it's an option, politely but firmly tell him you've already shown him how to fill out the form, and that he is on his own.
