Alan Lightman said this quote

Two men who had never seen each other before and would not likely see each other again. But their sincerity and sweetness, their sharing an instant in a fleeting life. It was almost as if a secret had passed between them. Was this some kind of love? I wanted to follow them, to touch them, to tell them of my happiness. I wanted to whisper to them: 'This is it. This is it'.
