The story of how Danny and I were married last July in a Manhattan courtroom, with our son, Kevin, beside us, began 12 years earlier, in a dark, damp subway station.

Danny called me that day, frantic. “I found a baby!” he shouted. “I called 911, but I don’t think they believed me. No one’s coming. I don’t want to leave the baby alone. Get down here and flag down a police car or something.” By nature Danny is a remarkably calm person, so when I felt his heart pounding through the phone line, I knew I had to run.

When I got to the A/C/E subway exit on Eighth Avenue, Danny was still there, waiting for help to arrive. The baby, who had been left on the ground in a corner behind the turnstiles, was light-brown skinned and quiet, probably about a day old, wrapped in an oversize black sweatshirt.

Peter Mercurio is a playwright and screenwriter whose latest screenplay is “Found (a True Story).”
