Edith Sitwell once received letter from a concerned reader. "Dear Dame Edith," it read. "As an admirer of your poems I am nevertheless greatly disturbed by a poem containing a line about the mating of tigers. I have a daughter of 19 -- at that age when the brook runs into the river -- and a son aged 10 who is very restless. I wish to entreat you, dear Dame Edith, when you write your poetry, to consider the disturbing effect that lines like those about the mating of tigers may have on the young." Edith's reply? "Tell your dirty little brats to read King Lear."
