What you meant and what landed

What you meant was stop. Get in the car. Do not hit your sister. Listen to me, because I have said it four times and we are late.

What landed was different, and it is worth separating the two, because the gap between them is the whole subject.

To a child, a shout is not information. It is a large person becoming suddenly unsafe. The words are almost incidental. What arrives is volume, face, and the fact that the person who keeps them safe is the source of it. That is why they stop, and it is also why the stopping does not teach them anything about sisters.
