Unprofessional? That’s a very corporate word for a moment of breathing. You’re treating an intellectual pursuit like it’s a board meeting. If they wanted a boardroom, they’d be in a boardroom with polished wood and silent air conditioning. But they're in a lab, or a studio, or wherever they are, and there, people exist. They have needs, they have habits, they have voices. You think silence is a tool they should master, but silence is just the absence of something. If they're working, they're working. If they're talking, they're talking. To suggest they need to perform a specific kind of quiet just to preserve some idea of "professionalism" is to ask them to pretend they aren't physically present. It’s a very artificial standard, Lena.
