Often in situations where you have to explain or argue a position, you have to be very careful to not become angry or irrational. The words you choose, the speed of your phrasing, and the volume you use will all contribute to the outcome. Therefore, it is best to stay calm, take deep breaths, choose words and phrasing that are short and concise, and be open to having to explain the situation a few times. Using these skills will enable a speedier outcome when arguing a position.
