You control your thoughts, your emotions, your responses to other, your decisions, how you treat others etc. Those should be the only things to concern you because that is what you can change/ correct or act on because it is in your hands, it is in your control. Other's opinions, emotions towards you, responses and what so are solely dependent on them and their beliefs in life, I believe other's should not ponder on things that they do not have control over, what's the benefit of that?
