Inside was a silver charm shaped like a swallow and a note from Evelyn.

Dear Poppy, it said, your grandmother and I had a music box with two birds on it.

We thought they were flying away from us.

Now I think they were showing us the way home.

Thank you for noticing when another person needed help.

Love, Aunt Evie.

Poppy wore the charm on a cord for a week, then asked me to keep it in her memory box so she wouldn’t lose it at school.

“You’re very wise,” I told her.
