When a stranger just comes out of left field and is rude to you he or she is already angry at something or someone else and you just happen to get in their way. 

It happened to my partner and me today when a woman started shouting at us at a red light. It was clear she was enraged but not at us. We were already stopped at the light when she drove up. When we happened to look over she just went ballistic. My partner and I both took a deep breath and ignored her. As soon as the light changed she floored it and sped away still angry at anyone and everyone.   

The key thing to remember is that when someone is so enraged they are willing to take it out on an innocent stranger they are not thinking. They are on auto-pilot of deeply wounded ego. There is no talking to them to point out how they are behaving. Most likely they are aware of their behavior but are blinded by their ego so they are looking for someone, anyone to pick a fight with. 

Don’t take it personally because when people do something like this they are directing their self-hatred outward. They are really mad at themselves and vomit their self-hatred onto others rather than look within to deal with the source of their pain.   

Love yourself more by being the emotionally responsible one and refuse to engage. No, it is not easy but it is definitely worth you taking the high road to not get involved with someone and their raging ego.
