Just now, however, I was closing the heavy sash window with a loud rattle, and a guy on the street heard the noise and looked up. A cool, long haired, indie muso type (thinking about it now, he looked a bit like Eric Balfour). He met my eyes and, unlike most people, didn't look away. So I smiled. A bit. He smiled. A bit. And gave me a little wave. So I gave him a little wave back. He didn't stop walking and after this two second exchange, he looked back at the street and I turned away from the window.
We'll never see each other again, and even if we did, would we remember? But that little connection, that unexpected moment of 'hello', it made me smile :)
