This is a love letter to the security staff member who came up to me when I was weeping on a couch at the National Theatre. He crossed the foyer, enquired softly if he could help, and when I said no, he specified that perhaps he could bring me some tissues.
Two and half months later, I bumped into him in the corridor on my last evening at the theatre as I was leaving.
I’m glad that I stopped and asked him if he had been the guy who’d shown such kindness to a stranger; How was he to know that I had been working there? There had been no evidence. I’m glad that I got to remind him of his generosity.
He saw and heard me one afternoon in the past. I am very glad that I got to look back at him.
Chok Notes to Self 
You could have called this “The Kindness or Comfort of Strangers”.
I don’t like that you were weeping, but I do very much like the story.
Very many years ago I was playing a solo stupid small boy’s game, which was to pedal a bicycle very fast down a slope in a road so that without any more pedalling I had sufficient momentum to carry me up and over two subsequent small hills in the road. I overdid my pedalling and at the end of the two subsequent hills I was feeling *very* faint and had to get off my bicycle and sit at the side of the road. (I forget whether or not I succeeded in my game.) A woman in one of the nearby houses saw me sitting at the side of the road, came out, asked me if I was all right, and invited me into her house to drink a glass of water. That’s almost all I remember about it, except that she had a non-english accent. I think (at any rate I hope) that it struck me at the time that I was being helped by a stranger who was also foreign: almost literally a Good Samaritan.
