Of course, he discovered us stealing pictures of him through the window, and was rendered uncomfortable (rightfully so). We had been caught. We had to apologize. He turned out to be a London gent who was very pleasant and forgiving, and even more fashionable than we had initially seen! He answered our questions and accepted our apologies and allowed us to take a picture of him. The right way.
So meticulously well-put together. So tall! So nice to meet you, sir.
