On Sunday morning, I found a mysterious envelope on our doorstep. Inside was a note that read: “Come with your son to the red limousine by Lincoln Middle School at 5 a.m. tomorrow. Do not ignore this. — J.W.”

My first instinct was to throw it away, but Ethan was curious and convinced me to go. At dawn, we drove to the school and were met by a man named J.W., a retired firefighter who had tragically lost his young daughter in a house fire years ago. He told Ethan that his courageous act had restored his hope and faith in others.
