My motto is to always treat others the way I want to be treated, irrespective of what they are doing.
We always have the choice to focus on the negative or the positive side, two sides of a coin yet glued together inseparably. Focusing on the negative only creates more of it and it is somewhat pointless, for it only adds on to our own suffering. Some will like it, others not. Instead of giving our power away on judging we should create own content.
