It is a human defect — to try to know one's self by the self of another. - Robert Penn Warren

The poem is a little myth of man's capacity of making life meaningful.

You grow up with somebody, and he is a success, a big-shot, and you're a failure, but he treats you just the way he always did and hasn't changed a bit. But that is what drives you to it, no matter what names you call yourself while you try to stick the knife in. There is a kind of snobbery of failure. It's a club, it's the old school, it's Skull and Bones, and there is no nasty supercilious twist to a mouth like the twist the drunk gets when he hangs over the bar beside the old pal who has turned out to be a big-shot and who hasn't changed a bit, or when the old pal takes him home to dinner and introduces him to the pretty little clear-eye woman and the healthy kids.

You meet somebody at the seashore on a vacation and have a wonderful time together. Or in a corner at a party, while the glasses clink and somebody beats on a piano, you talk with a stranger whose mind seems to whet and sharpen your own and with whom a wonderful new vista of ideas is spied. Or you share some intense or painful experience with somebody, and discover a deep communion. Then afterward you are sure that when you meet again, the gay companion will give you the old gaiety, the brilliant stranger will stir your mind from its torpor, the sympathetic friend will solace you with the old communion of spirit. But something happens, or almost always happens, to the gaiety, the brilliance, the communion. You remember the individual words from the old language you spoke together , but you have forgotten the grammar. You remember the steps of the dance, but the music isn’t playing any more. So there you are.
