Someone told me if you are late to a meeting, say "Thanks for your patience". I liked that and use it often. A Mefi whose name escapes me, when put in the spot. suggested saying "I don't want to give you my first answer, I want to give you the right answer, let me get back to you". I also liked that and use it often. What are the phrases you use at work that help better communicate / frame / set expectations / lead / work with your colleagues
