So, I would definitely do not say, I wouldn't say, I don't know the answer to that question. Once somebody asks me a question that I don't know the answer of, I would say something like, that's a great question and little by little redirect the question to something that I know and that I can speak of confidently and gives them proof of, you know. You got to be really slick with this. You got to be careful too because they're going to think you're not listening to them. So, if somebody's talking to me about something that I don't know, I just try to talk about it, repeat the question, repeat some things he has already told me and somehow redirect the question to something that I actually know about.
