Where the rule actually lives

A head teacher at a school in Amman decides that phones will stay in bags during the school day. She signs the letter, it goes home in every child's folder, and for about a week it holds.

Then it slips. Nobody overrules her. The parents simply decide, without a vote, that a child should be able to answer a mother at lunch. The older students decide the rule was meant for the younger ones. Two teachers quietly agree that a phone in class is fine if it is being used as a dictionary. Within a month the letter is still on the noticeboard and the phones are back on the desks.

It is tempting to believe that change starts at the top. Find the person who signs, persuade her, finished. But signing is not deciding. The person in charge usually chooses from a short list of options that everyone beneath her already finds acceptable, and that list is written by habit: what parents expect, what students will tolerate, what teachers say to each other by the kettle.

Authority sits in the office. Power sits in the corridor, at the school gate, in the parents' chat that keeps buzzing at ten at night.

So anyone who wants something to genuinely change, in a school, a street, a market or a family, would do better to start where the habits are made. It feels slower. It looks like a detour around the person with the pen.

It is not a detour. It is where the change actually comes from.
