I can get identicals becasue when someone starts acting like we act when its an aspect of ourselves we don't like its like a mirror and it can annoy. When my Duals annoy me its not intense, its more mild and circumstantial. The example I can dig up with the Dual that I love is that sometimes when he is explaining something that maybe I asked him about he will repeat himself. I feel annoyance. Usually its because we are trying to figure out something complex and I don't want too many words. But now I just say when he starts to repeat, "I got it; don't repeat it." Sometimes I realize he is waiting for my affirmation of what he is saying, so I quickly say when starts to repeat, "Ok. We won't do it that way. We are done with that." That way I will help him change his habit (over time!) and I am not annoyed. (And he feels free to tell me when he doesn't like something.)
