Here is the card.

That a scrap of cardboard could do that work — could hold a frightened child to the belief that he was worth keeping alive — humbles me still.

I had handed him that card the way you hand anyone a thing you expect to be thrown out by suppertime.

To me it was a formality, a daily nothing.

To him it became a talisman, a piece of ballast that kept a whole life from capsizing.

And that, I have come to think, is the terrible and wonderful ignorance we all live in: we can never know which of our small nothings is, to the person receiving it, the thing they will keep for fifty years.
