Recently I reread the adventures of Tom Sawyer after many years, and I was stunned to discover that Tom's summer vacation doesn't begin until the end of Chapter 21. Memory plays tricks. Tom's glorious idyll of mud, mild rebellion, chaste romance and rampant imagination electrified by a dash of danger and a blaze of heroismhad been filed in my mind under the heading of complete summer freedom. Even the most vivid scenes of Tom in school had been washed out by the brilliance of Tom barefoot and unbound.
