I think one of the things that needs to change in this world are peoples' attitudes about other people. The way you present yourself to another human being is evident, in my eyes, immediately. If you don't care about someone, it shows. This, then, makes the other person defensive, and so on and so forth. In the end you have two people aggressive and for what? That doesn't do anybody any good. It's ridiculous. If the first person comes with an attitude of respect towards this person, just as a fellow human being, then the entire scenario would play out differently.
I wonder if anyone has had that same issue, where someone just comes at you wrong? What happened? How might the encounter have gone if you were approached differently?
