Okay, so Bernie wanted to plug the breaking-things peripheral into my computer and I objected but then I let him but then it didn't work and then he said, "maybe you have to install the software to make it work" and I said, "did it come with software" and he said "yes" so I said "yes you have to install the software."
And I thought, "just how stupid is it possible to be, anyhow? But I didn't say it out loud.
Also he is mad because the computer diagnostic program doesn't seem to have worked any magic on his laptop and because I didn't see any error/diagnostic messages related to his problem.
Even though he gave me a pile of things to do today in his absence (in addition to actually creating an office out of this mess) calling me four times on his drive home to give me new things he'd thought of and didn't want to do himself, he seems annoyed that I didn't sit there and watch his computer for an hour to make sure--well, there's no telling what he thought I'd be able to do as I sat there watching a diagnostic I didn't understand try to make sense of a problem I wasn't clear about, but he clearly feels that had someone been sitting there watching the diagnostic program end and shut itself off, the results would have been different.
