Simone came with her mother and shouted, “That’s my scientist!” loud enough to make three people turn around.

Margo came too.

She had driven more than an hour after finishing work.

She stopped at my table, read every sentence, and asked serious questions.

Then she pointed to a small line at the bottom of the poster: “Emergency response begins when someone notices.”

“That’s a good conclusion,” she said.

I told her the line wasn’t really science.

It was something I wanted to remember.
