Lost in Atlanta

Question: What would you do if your child got lost in the largest airport in the United States? Would you panic? How would you get your child back? For a parent, this would be one of those worst case scenarios.
When I was returning home on my recent trip, I had a 2-hour layover in Atlanta. While I was in the airport, a very disturbing event happened. I was taking the subway tram from concourse D to Concourse A and had just gotten on the tram and turned around when I saw a mother and her 2 sons getting ready to board. As they approached the open doors, the mother paused to check on the child that was behind her and the younger one kept walking. Her delay put about 10 feet between her and her younger son. She looked up about the time the automated voice said the doors were closing and she made a mad dash to the doors but it was too late as the doors shut and her youngest son was separated from her. Seeing her fear, I motioned for her to stay there and I decided to return him back to her. Eric was 7 and in second grade but he was very brave in the presence of a tram full of strangers. It was my first time in Atlanta and it took me a stop to figure out how to go back the way we came. Eric and I got off the tram at concourse B and we got on the tram going the other way. When we got to the Concourse D stop we got off and went looking for the mom. She thought that he would get off elsewhere and had apparently taken the following tram to find him. We waited at the concourse D tram stop for about 5 minutes and no mother came and no one was visible at any of the other tram stops so Eric and I went upstairs.
We found a security guard who directed us to an airline kiosk on the concourse. I explained the situation and the attendant asked me my name. I thought that it might be comforting to the mom if she knew that the person taking care of her son was a doctor (Ph.D.), so I told the airline guy that I was Dr. Garrett. Eric also had a laminated card on his backpack zipper that detailed his address and phone number. The attendant called the number but no one was at his home to take the call. Eric didn't know his mom's cell phone number so the attendant decided to use the airport paging system. He called in the data and about 2 minutes later, a voice announced over the com system for Susan M. to please call 911.
Now, if you are a parent and you have lost your child, and a voice comes over the intercom asking you to call 911, are you going to be relieved or do you get more worried? When you make the call and find out that a doctor (Me) is currently with your child are your fears escalated even more? Maybe I should have used just plain Jim. In any case, we got a call from the intercom operator within 60 seconds of the announcement that his mom had called and was on the way.
Susan was easy enough to identify, she was the frantic looking lady with a single child in tow. I motioned to her and she looked really relieved. She came over and thanked me and began hugging Eric and telling him how worried she had been and how glad she was that she had found him. I left and went to my gate since I had used up almost all of my residual layover time. Thinking back, I still get a little disturbed when I consider how easy it would be to have that same scenario play out with our family. It's hard to keep them all corraled and you don't always have a free hand or a leash to make sure all are present and with the program. I think we'll be laminating cards with their name and address and our cell-phone numbers on them before we take a family airline trip.
