If you broaden your vision you will see this from a different angle. You will feel sorry for the person with whom you are getting angry. Their behavior is rude because somewhere in their psyche there is roughness, discomfort, and uneasiness. They have not received as much knowledge or love as much as you have. They don’t have that much wisdom, and that is why they are behaving in this way. When this understanding comes to you, then compassion also will come.
