Walter Mitty is an ordinary man living an ordinary life. But he has dreams - vivid, extraordinary day dreams - in which the life he leads is one of excitement and even adventure, in which he - a weary, put upon middle-aged man - is the hero of his own story.
A man can dream, can't he?
The Secret Life of Walter Mitty is just one of the brilliant humorous and witty stories written by James Thurber and collected here.
