ts like seeing a person you never saw before. You could be passing on the street - you look at each other for a few seconds and theres a kind of recognition. Like you both know something. But, then the next moment the persons gone and its too late to do anything about it. But, you remember it because it was right there and you let it go and you think, "What if I had stopped and said something?" It might happen only a few times in your life.
