Suppose you try to have a discussion with someone and you use one method (one approch to how to discuss – what to say, when, how to organize it, etc.) and he uses a different method. What happens? Chaos. Your step 1 and his step 1 don't match. Your step 2 and his step 2 don't match. From your perspective, he keeps doing the wrong things. From his perspective, you keep doing the wrong things.
So it's important to communicate about your discussion method and take an interest in the discussion methods of others.
