Many people, meeting Aziraphale for the first time, formed three impressions: that he was English, that he was intelligent, and that he was gayer than a treeful of monkeys on nitrous oxide.
Let us begin this letter, this prelude to an encounter, formally, as a declaration, in the old-fashioned way: I love you. You do not know me (although you have seen me, smiled at me). I know you (although not so well as I would like. I want to be there when your eyes flutter open in the morning, and you see me, and you smile. Surely this would be paradise enough?). So I do declare myself to you now, with pen set to paper. I declare it again: I love you.
