The total said out loud

In many neighbourhoods in Luxor, families buy their daily things on credit from the small shop at the end of the street. Bread, eggs, a packet of tea, a bottle of oil. Nothing changes hands but a nod, and the man behind the counter writes it in a thick book.

Each purchase is tiny, and that is exactly the trouble. A household can buy something small four times a day for a month and never once feel it. Then the month ends, the page is added up, and the number lands like a stone. Arguments follow. Sometimes a family quietly begins using another shop rather than face the page.

Some shops do one thing differently. Each time a purchase goes in the book, the owner says the running total out loud, or writes the new figure on a slip of paper and drops it in the bag. It takes him seconds.

It changes the whole month. What was gradual becomes visible. A mother hears the figure climb on a Tuesday and decides the biscuits can wait. Nobody is ambushed at the end, so nobody is embarrassed, and the family keeps coming back to the man who never surprised them.

We are poor judges of anything that piles up slowly or happens where we cannot see it. Small debts, small habits and small neglect all stay quiet until they are large.

The answer is rarely more willpower. It is a signal, placed where the person cannot miss it, that brings the end of the month into the present. Whoever bothers to make that signal, when nobody else does, earns something worth more than the sale.
