He leans in when you speak

Even an inch counts. The forward lean is the body's way of closing a distance it wishes didn't exist. It happens before the person consciously registers that they're doing it — the brain sends the command and the torso follows, chasing the voice or the presence of someone it finds compelling. Watch for the moment his upper body starts to angle toward you, especially in louder environments where leaning could be justified by acoustics but is actually driven by something else. The lean is particularly telling when it's sustained — not a single dip toward a punchline but a general orientation that keeps gravitating in your direction throughout the conversation. That sustained posture says the body doesn't want the encounter to end. It's trying to stay inside it for as long as possible. The forward lean is the body doing what the voice might not yet be saying: don't stop, I want more of this.
