A record you can erase isn't one
Cut a tree across the trunk and every year it lived is there, in order, in rings.
The wide rings are the wet years. The thin dark bands are the droughts. A fire leaves a scar the wood grows around and never closes — a black seam held open in the grain for as long as the tree stands. The tree cannot go back and widen the lean years. It cannot make the fire look like it missed. Whatever happened is in the wood, at the depth where it happened, under everything that grew after.
We build our records to be erasable and call it convenience. A number comes in wrong, you open the row, you fix it, you save. The bad year, smoothed over. Nobody meant anything by it. That is the danger — that nobody means anything by it. A record you can quietly correct is a record that can quietly change, and after the first quiet change you cannot tell the corrected entries from the true ones, because correcting left no mark. The book still balances. It has only stopped being a record of what happened and become a record of what you would rather had.
So we stopped erasing. A wrong line stays; a new line goes under it, pointing back, saying this replaced that, on this day. Each entry carries a fingerprint of all the entries before it, so that reaching back to change an old one breaks every fingerprint that came after, and the break shows. You are not asked to leave the past alone. You are made unable to touch it quietly.
It feels like losing something, the first time you cannot reach in and fix the number. It is the opposite. The fire scar is not the flaw in the trunk. It is the most honest thing the tree has — the year it nearly did not make it, carried in plain sight, grown around, never sanded out, still there when the tree is the tallest thing on the ridge.
The good years keep themselves. A record is what you do with the bad ones.
