So the people who MUST have the last word about something reveal something about themselves. They reveal that they NEED to be right, and they need that verification and validation socially and interpersonally — not objectively, like the person with authentic self-esteem.

Other motives exist for wanting the last word. One is a false belief that, “If I said it last, then that means I won. My opponent has no answer.” That’s not always true. Sometimes people give up talking to you because they cannot counter what you’re saying. But that still doesn’t make you right. And sometimes people give up because they’re convinced you’re not hearing them, or replying to their most important point. So they see you as hopeless on the issue. Or maybe just annoying.

Don’t flatter yourself merely because you got the last word. It doesn’t make you right or credible.
