Here is a story of a London "nut" who had mounted guard for the first
time:
The colonel had just given him a wigging because of the state of his
equipment. A little later the colonel passed his post. The nut did not
salute. The indignant colonel turned and passed again. The nut ignored
him.
"Why in the qualified blazes don't you salute?" the colonel roared.
"Ah," said the nut, softly, "I fawncied you were vexed with me."
