I understand what you are going through, I have lost several pets throughout my life, I know very well the pain that is felt, and how it affects as time passes.
There are so many things that are not right in the world, that many people do not feel well emotionally, which is the beginning of aggression, you do very well in trying to ignore people who are hostile, since an argument leads to nothing, and the aggressive person manages to vent his anger, and then the one who is left behind is the other person
