I fell in love with Susie sixty-seven years ago, as a boy of fourteen. [She was an older woman, fifteen. This was a continuation of a long family tradition -- my mother was a year older than my father, and his mother was a year older than his father.] As high school students "going steady" [yes, we did speak of it that way then], we listened to the music of Bach and read the poetry of e. e. cummings.
Today, I have been a bit down, and in an effort to pep myself up, I said to myself, "Cheer up. Toujours gai." This was an evocation of the old newspaper columns by Don Marquis, actually before my time, relating the doings of a cockroach named archy and a cat named mehitabel. ["Toujours gai " was mehitabel's signature line.] Archy, who in a previous life had been a free verse poet, lived in the newsroom of the newspaper for which Marquis worked. At night he would write poetry by throwing himself on the keys of the old standard typewriter at Marquis' desk, one letter at a time. Since archy could not simultaneously hit the caps key and a letter key, all of his poetry was lower case.
It has been speculated, but alas without any evidence, that archy inspired cummings to write in lower case as well.
