Does s/he have a technical or business background? I once corrected my manager when I was contracting at an Australian ISP. It was something about browser cookies I think. As soon as I told him he's wrong, (we were in a pretty open-plan albeit half empty office) he just stopped talking, turned his chair around and went back to work. I asked him if he had things for me to do for 3 days always with responses of just "no", before I contacted by contract manager (affectionately referred to as "pimps" in Australian contracting) and explained the situation. Later that day the manager turns to me and says I did the wrong thing by talking to my pimp - I should have talked to him directly instead. The irony was lost on him I think. Anyway. I'd still do the same thing in that situation (technical discussion that affects work). But if a guy who doesn't actually do the technical work insists on saying "depreciated" instead of "deprecated" or "jdk" instead of jvm, but others know what he meant, it's probably harmless.
