This is pretty unlike regular life. As an engineer if someone asked me "Hey, in order to get the widget-spinner to go clockwise do I call function X?" I might answer "No, what you need to do is set variable X to true." (or whatever). In a deposition the correct answer would just be "no."
I was in a patent troll deposition once and the opposing attorney kept dancing around moderately close to the interesting stuff but never really got there due to the fact that he didn't really know what he was doing. It was kind of fun just saying "no" over and over again without giving him any additional context or help. Weird though. It's not how humans normally communicate.
