I can honestly say that I've never achieved whatever it is some people call closure by "telling someone off", "showing them", etc.
I guess immediately afterwards you might feel really good about yourself because you were able to make someone else angry, or making them feel bad.
I mean, it's not like you're going to say this perfect something and the other is going to stand there gob smacked, unable to think of anything to say back to you.
If they don't respond, it's because they really don't care or haven't been influenced one whit by your dressing down, and can't waste their time.
Then, that other person just continues to exist, living their life, and you know they are doing just that.
I don't think one closes the door on something in general. It just sort of drifts shut by itself when you stop holding onto it.
