Depict a brief sketch of the nature of Tom Sawyer.

Mischievous but lovable, Tom Sawyer is a fictional character so well known that he has become a folkloric figure. Even those who have not read The Adventures of Tom Sawyer may be familiar with the episodes in which Tom tricks his friends into whitewashing his aunt's fence for him, spies on his own funeral, acts as the surprise witness against Injun Joe at Muff Potter's murder trial, and gets lost in the cave with his beloved Becky Thatcher. Tom's Aunt Polly takes good care of Tom and his half-brother Sid, although often Tom exasperates her when he gets into trouble. He sneaks out his window at night to go on adventures with his friend Huck Finn, believes in superstitions, and yearns to lead what he sees as the exciting life of a pirate or robber. He can't sit still in church or in school and always finds some diversion, such as watching a bug, to make the time pass more quickly. Tom is happiest when he is off having thrilling adventures with his friends: searching for buried treasure, running away for a few days to a sandbar in the Mississippi River in a game of pirates, or hiding in the cemetery at midnight. He adores Becky Thatcher, the new girl in town, and shows off to get her attention. Tom is a boy of strong emotions and great imagination, and in spite of his mischievous ways he has a good heart: his rescues of Becky when she is heading for trouble with the schoolmaster and of Muff Potter when he is on trial for murder show that Tom knows the right thing to do.
