Kindness has terrible record-keeping. You held a lift for someone with a pram this month and have no memory of it. You sent the message nobody required you to send. You let a car in on a roundabout, in traffic, when you were already late.
None of that got stored, because it cost you nothing you noticed and there was no moment afterwards where anyone stopped to mark it.
Meanwhile the one sharp thing you said in 2019 is filed permanently, cross-referenced, available on demand. The archive is lopsided. It is not a fair summary of the person keeping it.
