I've been told by people I trust, that I consider wise, that you should always assume the best. Maybe they had a bad day, maybe they are smarter than you and its you that can't understand, maybe they are trying but their own life is at a low point. I've been told that believing in the best of people will bring grace into your life. I don't know if that is true. What I do know is that every single time - every time - I assume bad intentions, it sours me, makes me less than I could be, and nothing good comes from it. Assume the best. We are all still people and still trying.
