The place I'm most likely to learn this lesson is when I closely observe my men friends interacting with their wives or partners. Whenever one of them interrupts, finishes a sentence or story, or steals a punchline, I'm reminded how rude it is, i.e. how rude I can sometimes be. And that's not the worst behavior I've observed in others that chastens me.
I think of myself as a good listener. When my wife and I are alone, I'm much less inclined to engage in some of the poor listening or disrespectful behaviors I find obnoxious in others. But clearly I've still got some work to do. I don't relish the idea of becoming an example to others of what not to do.
