It is Christmas Eve, 1799, and Dorothy Wordsworth is awake in the dead of night. She stands outside in the winter cold, waiting patiently. When the new day breaks it will bring family and friends to Dorothy's door. For tomorrow is a double joy: tomorrow is her Christmas Birthday.Carol Ann Duffy's wonderful new poem takes us to the frozen landscape of the Lake District, where a merry celebration is about to begin in the Wordsworths' cottage.
