Just because you said it doesn’t mean they heard it. Communication counts when it lands, not when it leaves.

Sending and landing are separate events, and only the second one counts. You can deliver a perfectly accurate sentence into a room where someone was distracted, defensive, or hearing a different meaning in your words, and nothing has been communicated. Responsibility for that gap is uncomfortable to accept, because you did say it. The purpose was never to have spoken.

Check rather than assume: ask what they took from it, in their own words. If the answer is not what you meant, try again differently instead of repeating yourself louder. Treat being understood as the finish line.
