He spoke at my university and said something that stuck with me, “never ask a question to show that you know something, but always ask in earnest and be vulnerable to the fact that you don’t know something.”
A little aside--I have a colleague who will ask a question, and then they ask another one, at which point you realize they already have an answer. HA! Just tell me the idea. Don't manipulate like a child. Magic spell to make their conclusions inevitable, because you answered two leading questions.
Bravo Milton.
And when I don't ask questions, but assume the other parties already knows what I know, I get problems. So... I have to find a way to ascertain that other parties know what I know (more or less) - without sounding like I'm asking a question to show what I know.
