Recently I read a book called Vanished Parts of Yesterday by Lord Frederick Hamilton. In it he tells the story of Catherine the Great - who, when she found the first violet of spring, ordered a sentry to be placed over it to protect it from being plucked. Forgetting to rescind the order, day and night, summer and winter, a sentry stood where 150 years ago, a violet bloomed. The new generation did not know why the sentry was there and he didn't either. It was simply a tradition!
