Every interruption quietly says, “What I’m about to say matters more than what you’re saying.”

Cutting in makes a claim about relative importance whether or not you meant one. The other person feels the ranking immediately, even when your point was good and the timing was only enthusiasm. Over time it teaches people to keep their contributions short around you, and the room gets quieter in a way nobody explains. The habit is usually invisible from inside.

Count your interruptions for one meeting, honestly. Hold the thought and write it down instead of releasing it. If you do cut in, say so and hand the floor back, which repairs most of it.
