Example sentence: 'Royal Beatings' was my first story, and it was published in 1977. But I sent all my early stories to 'The New Yorker' in the 1950s, and then I stopped sending for a long time and sent only to magazines in Canada. 'The New Yorker' sent me nice notes, though - penciled, informal messages. They never signed them. They weren't terribly encouraging.
