The Great Gatsby is a novel written by F. Scott Fitzgerald, first published in 1925. The novel is set in New York and Long Island during the summer season.
The quote “I hope she’ll be a fool—that’s the best thing a girl can be in this world, a beautiful little fool” is from a letter written by Tom Buchanan to Nick Carraway, which describes Daisy’s marriage to Gatsby.
In this quote, Tom Buchanan expresses his hope that Daisy will be an ignorant woman who will not question her husband or the way he treats her. He hopes that she will remain ignorant so that she can live happily in her fantasy world rather than face reality and become unhappy.
