Yeah, once I was in a boardroom where two partners were arguing over a budget cut. One of them kept fidgeting, the other avoided eye contact. I just said, “Let’s take a breath and focus on what’s really at stake,” and it broke the tension. A quick read between the lines and suddenly they were negotiating in good faith. If you can tweak a sensor to catch those micro‑clues, you’ll probably be the one pulling the deal together.
