Tension is running high right now, and you’re going to have to put extra effort into not flying off the handle when someone says something rude. Give people the benefit of the doubt, especially the newer people in your world. They might not know the rules, and it’s really not up to you to teach them. This person will learn the lessons they need to learn eventually, and it’s best for you to walk away from any drama they create. You don’t need it.
