A.A. Milne, Autobiography. New York: E.P. Dutton, 1939, pp. 131-132—
One way and another we [the author and his brother Kenneth John Milne] got a good deal of happiness out of it [preparatory school], if not always in the way expected of us. We sat together now, never to be separated, in the Mathematical Sixth, which meant that we occupied one corner of a room in which some lowly mathmatical set was being taught. Since we could not talk wthout disturbing the master-in-charge we wrote letters to each other: long letters detailing our plans for the next holidays. Interest was added to these letters by our custom of omitting every other word, leaving blanks which the addressee had to fill in. Our minds were sufficiently in tune for this to be possible without being easy; one could get the general sense without being certain of the exact word. As in my old French set, we then changed papers and marked each other's mistakes. Sometimes our communications were in initial letters only. During “second school,” for instance, it was certain that one of us would ask the other “SWGUSIB?” This clearly meant “Shall we go up-Sutts in break?” a question which expected the answer “Yes” and got it. Ken would feel in his pockets and decide that, since we already owed Father 15/6, we might as well owe him sixteen shillings. We did.
