Part of your duties as a rational, social human being is helping and teaching others. Persuade as best you can. But if they remain unchanged and unpersuaded, you do not get offended or hurt.
Rather, you pivot. You pivot to another form of persuasion or you pivot to a different action or you pivot and begin to exercise virtue, such as patience.
Life is like Jazz and is not linear. You may have a vision or an idea of how things will go. You may plan to the n-th degree. But in all this complexity, things are subject to change. You don't freak out like a little girl who doesn't get candy when her mom says no to her while they are shopping. Rather, you accept whatever happens and pivot.
