Unexpected faces in familiar places - do you remember me? Half smile among the stacks - an acknowledgment, or some private joke within your mind? You may change the colour of your hair, but that won't make me mistake you for someone else. I know that smile, I know those eyes, the same now as they were then. I hope you do well, whether that half smile was for me or not. The past is the past and we were never going to be anything other than passersby in one another's lives, even if we have a whole city and still manage to find one another.
