If you end up dealing with an arrogant person today, try not to let their bad behavior tarnish who they are in your eyes. Sometimes when people get put into a difficult situation, they lash out and act defensively or impolitely. Perhaps this boorish person is just feeling insecure. Try to understand that one encounter won’t give you a complete idea of who they really are. Give this person another chance to impress you. You will be very glad you did.
