Is it possible you don’t have the answer?
When we don’t have the answer, it is the reason we seek an expert. Positioning with the expert that we know something and forcing the dialog around what we know can limit the greater potential, or even success or failure for the endeavor.
Posing to align yourself as equal with the expert is dangerous. First there is a reason why they are the expert. Second, there is a reason why you engaged them in the conversation. Let the expert be the expert and get out of the way. It will bring more satisfying results for you and the expert.
