I did not answer immediately.

Noah was at the table, drawing a diagram of a small electric motor for a science assignment.

He looked up and asked whether I would show people how to keep a generator outside.

I said that was the most important part.

He asked whether I would explain how to use a transfer switch without sending power back into the utility lines.

I told him I would explain why that work belonged to a qualified electrician.

He nodded with the solemn satisfaction of someone who had just passed a test.

Then he asked whether he could come along and help.

I looked at Rachel, who lifted one eyebrow over her coffee.

For a long time, I had thought the best thing I could do for Noah was make the whole episode disappear from his childhood.

He was telling me, in his own quiet way, that he wanted to turn what he had learned into something useful.

I called the number on the postcard that afternoon.

The coordinator was a woman named Denise Carver, who worked for the county’s emergency management department.

She had a practical voice and the habit of asking one question at a time.

Denise said the previous winter had exposed gaps in how the county helped residents who depended on electrically powered medical equipment.

The department had arranged a demonstration with the fire service, the utility company, and several local suppliers.

She wanted someone who understood machines but could speak without making people feel foolish.

I asked who had recommended me.

She said Gerald Pike had given her my name.

I could almost hear Gerald clearing his throat behind his shop counter and insisting that he was not doing anyone a favor.

Denise told me there would be no need to discuss the incident on Alder Ridge Road.

I thanked her for that.

Then she said the one thing that made me agree.

She said some of the people attending had never owned a generator and were frightened of making an expensive mistake.

I knew exactly how that felt.

I agreed to bring my machine for a static demonstration, provided that we kept it shut down inside the building.

Denise said the fire department would provide an outdoor demonstration area for any equipment that needed to run.

We arranged a time to inspect the site together.

After I hung up, I found Noah waiting in the doorway.

He had heard enough to know that I had said yes.

He asked whether he could make a sign about carbon monoxide.

I told him he could make two signs if he wanted.
