Bad conversation leads nowhere. It seems as though when you leave this sort of discussion, the activity level of the entire group drops. That’s okay, but also speaks to a disparity—your talking was filling up the group with talk, but mostly with your own words. Learn to spur other people on with as few words as possible. Yield to them. When the conversation is boring, so what? It’s not your job to change it to be better or more right. Your primary role is to listen.
