We should notice and learn about the origins of our behavior
We can remind ourselves that our circumstances have changed: the dangers that gave birth to our complicated manner of expression are gone. People won't get upset if we tell them how we feel. And if someone does, then as a final option, we can always walk away.
We should be able to recognize that our complicated behavior doesn't please people in reality; most of the people we deal it would prefer to hear our true opinion, even if they get frustrated with it at first.
