When you feel like someone’s done an injustice to you, before attacking them or getting angry at them, give them the benefit of the doubt.
They probably aren’t doing it on purpose. They could be experiencing significant problems, they might be missing a critical piece of information, or they might have an entirely different perspective which makes them take an alternative (maybe even better) approach.
Give them the benefit of the doubt. You would probably want it yourself if you were in their position.
