I think that to be sweet is a very good option. Being patient and kind is a great skill that we should acquire. But sometimes reality is harsh. And we should communicate this harsh part of reality too. We don’t live in a perfect world, where everyone is honest, kind, or altruist. Besides people often refuge in a utopic, ego-centric world and they consider themselves too important.
If you care about someone, you need to shake this aspect of reality or human behavior sometimes. If you make people think that they are too important or that everything will work fine even though wrong behavior, you aren’t caring about that person anymore.
We need to speak the truth sometimes and this truth is often, inevitably, expressed brutally. It’s very difficult not getting things personally when you are communicating the truth, (or at the least, “your truth”) to other people. Often conflicts arise. But these conflicts are necessary for us and other people to grow.
I think a great objective I can put in my life at the moment is to be assertive avoiding as much as possible being brutal. And above all, I shouldn’t get things personally and always remember I could be wrong. In this way, I can improve myself and the people I’m connected with.
