One of the things that I find difficult to negotiate is people who go off topic. It's not possible to arrive at any sort of consensus when people consistently go off topic. People go off topic for various reasons: 1. They have a pet grievance, and they use every topic to air that grievance. 2. They don't have anything to contribute on that topic, but they want to be part of the conversation so they change the topic to something which has a similar word or theme. 3. They find the topic unpleasant and want to change the direction of the discussion. How important is staying on topic to you?
