I think some people just talk at you, mainly about themselves. We had some friends stay with us prior to going to live the other side of the world, they asked if a friend of theirs, who we knew, could pop in to say goodbye as she was passing our area. She stayed for 2 hours talked non stop, about her, her house, her aging parents, her children, their relationships, their jobs, her job.......on and on she went hardly pausing for breath, didn't ask anything about any of us. I was tempted to say "well that's enough about you, let's focus on our friends here, who, as you know, are going thousands of miles away to live" I do wonder if some people know that they are delivering a monologue and haven't grasped the concept of a two way/or more conversation.
