If people around you overreact to an unpleasant situation today, do not follow their example—no matter how justified they may be. Screaming at someone who has been rude or inconsiderate isn't going to mitigate the stress; it will only increase the tension. Be mindful of your role in every conversation, and try to be a force for mutual respect. You will have to take the high road today. There will soon be a day for you to get some things off your chest.
