Huckleberry Finn and Tom Sawyer are two friends with very different personalities, each bringing their own unique characteristics into this comical relationship. Tom and Huck are two adventurous souls but in very opposing ways. Hucks idea of adventure is to escape from society, their beliefs and all of their conformities, but he does it in a way that is level-headed and sensible.
Tom, on the other hand, is more likely to make up an adventure based on something he had read in a book and not really trying to escape anything. All of his ideas and schemes come from books, unlike Huck, who has actually lived the fantasies Tom has imagined. The two are alike in one way though. They both have a very strong sense of adventure. I think this one trait along with their similar ages is what makes them friends.
Huck seems to be the kind of person that Tom would want to be friends with because of his willingness to make other people happy. Tom lives out his escapades with no regard for the pain and suffering it causes others. Huck, on the other hand, just wants things done and done right but he gives into Toms wild ideas and extravagant plans, which Tom loves. Tom and Huck are two interesting yet different characters. It is for these reasons that they have become an American literary classic.
