The Modern Translation
Cicero's point is that the person who commands a room is not always the one making noise. Apply that to Dale's eleventh minute. You cannot out-talk him, and trying to will only give you two people talking over slide six. Instead, practice the quiet art on purpose. Stop fidgeting with your cold coffee, hold your pen still, and let one clean pause arrive. Then, in the first gap, say his name once and offer one sentence: "Dale, I want to make sure we hit item four before 10:45, can I take two minutes now?" Silence did the heavy lifting here. It showed you were listening, which earns you the right to interrupt, and it made your one sentence sound calm instead of annoyed. Rooms tend to reward the person who waited and then spoke briefly. Your agenda item should fit in the gap he gave you, and the meeting will likely thank you for it.

In your next meeting, write your one point on a sticky note before it starts. When someone runs long, stay quiet and still for five full seconds, then say their name and make your point in one sentence. Afterward, notice whether people leaned in more than when you have jumped in mid-sentence, and whether the pause felt shorter than it seemed.
