This poem is a parody by Lewis Carroll of "Resolution and Independence" by William Wordsworth. Its full text in conventional spelling and information about its background can be found in Wikipedia. Carroll’s choice of words and rhyme is masterly. And the theme of not listening to other people’s problems, until they mention something that interests the listener directly, is a bittersweet and powerful one.
