Living and working in that shared area which we can call, "our space", has some unwritten rules. While it can sound out of date, being considerate is essential. Whether we like it or not, what we do and say in that shared area is seen, heard, assessed and YIKES... even judged by others.
How to navigate the sometimes rough waters? What I tell my audiences, whether they are executives or the executive assistants, "Do what you think would make your favorite grandparent proud of you." That's what I do and it works for me, too. Sometimes I "see" my Mother's father, tellling a story and making us laugh and it inspires me to do the same. I can just "hear" my maternal grandmother say, "that's wonderful, let me give you a hug," upon hearing some good news from or about me.
But what is important is to be considerate of others in our shared spaces no matter who we let inspire our best behavior. That shows maturity, teamwork, the ability to compromise and honor boundaries. How can it be anything but good to be thought of as thoughtful???
