It was a small thing. It happened outside the chicken shop on a Friday night.
A kid — twelve, maybe, all elbows — came out with a box of chips and tripped on the kerb. The chips went everywhere. Across the pavement, into the gutter, under a bike. The older boys by the bus stop cracked up laughing. One of them filmed it. The kid’s face went red, then hard, the way kids’ faces go when they’re trying not to cry in front of people.
Marcus was coming out of the shop behind him. Twenty-four, dark clothes, quiet. Some of those older boys knew who Marcus used to be. They stopped laughing quite so loud.
Marcus didn’t say anything to them. He didn’t make a speech about filming people. He just went back into the shop, bought another portion of chips, came out, and handed them to the kid.
“There you go.”
The kid stared at him. “I haven’t got any money.”
“Didn’t ask for any.”
That was it. Marcus walked off. He didn’t look back to see if anyone was watching.
A week later, Marcus was on the top deck of the 36. It was rammed. An older woman got on with shopping bags and there was nowhere to sit. People looked at their phones.
And then a kid near the front — twelve, maybe, all elbows — stood up and said, “Here, you can have my seat.”
Marcus recognised him. The kid didn’t see Marcus. He just stood holding the pole, swaying, while the woman sat down and thanked him.
Marcus looked out of the window and didn’t say anything. He’ll probably never know if the chips had anything to do with it. That’s how ripples work. You drop the stone. You don’t get to follow the water.
