I don't think I knew any of my father's friends - male friends - by their real names. I remember them only by their nicknames.
That is why I think, in defiance of Plato, that there is at once error and vulgarity in saying that poetry is a lie, except in the sense that Cocteau wrote one day: I am a lie who always tells the truth. The only poetry which lies purely and simply is academic, pseudo-classical, conceptually repetitive poetry, and it is not poetry.
