Be you. Be your authentic self and you can relax by not having to act differently in different situations. "Practicing these principles in all our affairs" means living the steps and living recovery in your daily life. The holiday's can prompt people to put on facade. This is okay, as long as it doesn't lead to disappointment as that can cause a chain of events that can end disastrously. Most of us, especially in recovery, can tell right away if someone's real or if they're putting on an act. Acknowledging that they're on their own journey and not letting it affect you and your journey is paramount.
