A Smile Card experience

Eight years ago I met with a group of friends and one of the results of that meeting was the concept of Smile Cards.  Since then the project has blown up far more than any of us would have imagined.  However, the one thing that I have never experienced is a "random" Smile Card experience where I saw a stranger with one of these cards.  The night of the Ikea furniture assembly from the previous post the HyWy and I went to dinner at a neighborhood pizza joint, which we had never been to.  We sat down in exhaustion and just wanted to eat our food.  While waiting for our order the next customer came in and sat down by himself with a book across the aisle from us.  I was standing at the counter waiting to get a refill when the HyWy got my attention and gestured towards this customer.  Immediately my attention was drawn to his bookmark, a Smile Card.  I cannot describe the feeling I felt then.  It was a blur of emotions and flashbacks through eight years of meetings, design iterations, experiments in kindness, tags, stories, and connections.  I wanted to ask the gentleman how he came across the Smile Card, to connect with him, and tell him my story but then I thought the beauty of the moment didn't need to be clouded with all of that.  The serendipity of the moment was the perfect complement to the serendipitous feeling I get when tagging someone with a Smile Card.
