Don’t listen to him OP. You are gonna need to hype yourself up for what comes next. Think of all the times you were disrespected in life. That asshat is only going to respond to aggression. Don’t forget to breathe, like a lot, before pounding on his cab. Like try to be out of breath before he opens his door so he knows you just got your swole on. Swear words are your friends. If all else fails start trembling like the Hulk in you is about to be released. Remember, you are in a stand your ground state. You can use deadly force even if you instigate the confrontation. Your hands are your lethal weapons. You can move like Neo in the Matrix. If you believe in yourself you can kick him in the face after a forward somersault. People always go down after one hit like in the movies, you are star in this movie called life and he is just thug #3 whose only point is to fall at the almighty power of your open handed judo chop. Now go out there and don’t forget to get it all on camera so we can bask in your glory.
