It starts innocently. Casually. You turn up at the annual spring fair full of beans, help with the raffle tickets (because the pretty red-haired music teacher asks you to) and win a bottle of whiskey (all school raffles are fixed), and, before you know where you are, you're turning up at the weekly school council meetings, organizing concerts, discussing plans for a new music department, donating funds for the rejuvenation of the water fountains—you're implicated in the school, you're involved in it. Sooner or later you stop dropping your children at the school gates. You start following them in.
