There is a layer of English society - or perhaps several overlapping onion-like layers - which floats.
I exaggerate, of course.
But there is a level of intelligent, sophisticated and moneyed English people who glide through life. They may not feel they have money; they may even struggle financially; but they know they have the security blanket that they are never going to fail utterly and end up in the gutter with no friends, desolate, unable to keep body and soul together.
This last week, I went to the Sohemian Society for the first time and I think that layer was visible. The Society is ostensibly a celebration of the culture and history of Soho, which has always had a Bohemian element to it. But Soho overlaps into Fitzrovia and both those areas attract interesting people. Perhaps half or more of the audience, though, had never heard of the Sohemian Society; they had come along specifically to see the speaker that night.
Before the talk started, a couple of women behind me were chatting about the actress Dulcie Gray, whom they had known; the very amiable man who sat next to me turned out to be the editor of a very exclusive reference book; the speaker that night, Andrew Barrow, had written a biography of Naked Civil Servant Quentin Crisp whom he and others in the audience had known.
Of course, grim reality enters into everyone's life. Dulcie Gray died earlier this month aged 95 and, alas, was mostly forgotten by Middle England. The very exclusive reference book edited by the man next to me - like all reference works - is under an economic sword of Damocles held by Wikipedia and the internet in general. And Quentin Crisp died twelve years and one day before the Sohemian Society meeting, now just a footnote in English social history, perhaps even seen as a fictional character in some long-ago gay film - Didn't he appear in that chest-buster scene in Alien?
And then there are the melancholic memories of what might have been but never was. The would-be Icarus characters who might have flown through English artistic life and might even have missed the sun but who never even took off.
Author Andrew Barrow was talking to the Sohemian Society (which is open to all - anyone can wander along) about his book Animal Magic: A Brother's Story
It is about his brother Jonathan Barrow, who was killed with his fiancée in a car crash just a few days before their wedding in 1970. Jonathan was aged 22 and, a few days after his death, Andrew found the manuscript of a very bizarre novel Jonathan had recently finished writing.
In The Queue, Jonathan included several mentions of head-on car crashes and, in a another scene, there was another dark premonition of what actually did happen after his death. The church booked for his wedding ceremony did become the venue for his and his fiancee's funeral.
Their funeral was just a few days before the day on which they had been going to be married.
Judging by the extracts read by Andrew, The Queue is wildly surreal, featuring a cast of humans, animals and hybrids.
When Andrew showed the manuscript to Quentin Crisp shortly after Jonathan's death, Quentin said: "Your brother looked healthy, happy, natural. He could have played head prefect at Eton. But everything else about him is extremely odd. Not faintly odd. Extremely odd."
The Observer has said the book treads the thin line between "brilliance and total barminess".
The Independent on Sunday says it is "a wild picaresque fantasy, erotically polymorphous ... with a cast of bizarre humans and talking animals".
That would be the hens and stoats and toads and suicidal owls, a central dachshund called Mary who is an alcoholic drug addict and extremely promiscuous, a spineless hedgehog, a human sheep old enough to remember Disraeli and a fish specially-trained by the police for "complex underwater retrievals" which gets lost down the drain in a dirty bookshop in Soho.
Not your normal novel, then.
Though very English.
Someone in the audience asked Andrew if he thought it would have been published if Jonathan had lived. The answer was yes, almost certainly, because Jonathan (who had a job in advertising) knew lots of publishers.
Jonathan Barrow, it seems to me, was one of those people who would have glided through life; he seems in retrospect to have had a wonderfully artistic and creatively fulfilling future ahead of him, gliding through English society.
But, in a handful of seconds, his timeline stopped.
It can happen to anyone.
Ars longa. Vita brevis.
The sword of Damocles hangs over everyone's head, held by a thin thread.
Andrew Barrow has now had Jonathan's book published.
And his own book Animal Magic - about Jonathan and about The Queue - has also been published and been described as "a funny, dark memoir. Think Tommy Cooper describing a painting by Hieronymus Bosch."
Which may be a good description because, in his youth, Andrew tried to be a stand-up comic - mostly, he says, by nicking Tommy Cooper's gags.
He admits he was awful.
But he himself is almost as interesting as The Queue.
He is intelligent, sophisticated, witty and a good writer.
He has lived.
Country Life magazine described Animal Magic as "Deft, witty and poignant".
The Lady wrote: "This book ultimately belongs to Jonathan, and it is testament to his sibling's skill that he appears here so vividly, his supreme peculiarity preserved".
To the Sohemian Society, Andrew Barrow said: "If just one reader writes to thank you and say they enjoyed a book you have written, it makes it worthwhile. You hope to make them laugh. If they laugh and cry, that's even better."
God bless Englishness.
