The same “pass the salt” can be friendly or a declaration of war. Families hear the difference instantly.

Families run on a decade of accumulated tone. People who have lived with you have heard every version of your voice and hold an index of what each one means, which is why a neutral sentence can carry a whole argument at your own table and none at all anywhere else. It also means you cannot hide a mood at home, however careful the words are.

If you are carrying something into dinner, say so plainly rather than letting it out in how you ask for things. If somebody’s tone lands wrong, ask instead of answering it. Families read tone accurately and guess at the reason badly.
