The wall did not forget. The file did not forget. And when Eli grew old enough that his own hands trembled, he visited the murals in the vault and the ones out in the alleys and found, each time, a new shape pressed into the paint: a thank-you, a fingerprint, a folded photograph. He left behind small things in return—seeds, matches, a blue ribbon—and trusted that someone else someday would come by, press their palm, and be remembered back.
