1pm and on: Explaining in detail tools and procedures. Sometimes things are less obvious than expected, sometimes challenges are big enough to keep people from feeling comfortable with what they're supposed to do. In all cases, outcome is a weird mix of unsafety and uncertainty, and a mental eye sees estimates explode and timelines break. (Standing next to the playing field, watching opposing players run for an imaginary ball, and wondering whether this day has seen enough weak analogies of people moving in real-world space.)
