Very cool story!
You know, the general public likes you and kids love you, if you just
let them.
You have time to say hi, you have time to help someone find their way in the airport, you have time to do a thoughtful, concise PA.
People are going to automatically look up to you until you give them a reason not to. I've done quite a bit of PR work this year as a volunteer and you would be amazed how many times I've heard from people that they really didn't expect a pilot to address them as a person because, unfortunately, too many of us give the impression that we're unapproachable or "above" everyone.
All kinds of magic things start to happen if you just take the time to make yourself seem human to the flying public!
