In what ways are Buck and Huck similar?

First off their names is the first thing that jumps out to everyone as they are only different by one letter. Huck's and Buck's personality, general lifestyle and mind spirit is also quite similar. They are both two extremely adventurous individuals with a violent mind. They are attracted by doing dangerous things and getting involved into different adventures. Buck and Huck are also similar to one another because they have things in common such as that both of them are raised in a very nice household. But although they have all these nice things for them they rather be out in the wild. Huck and Buck are somewhat forced to live in a wealthy well behaved civilized society but its not what they want; for the both of them. They are different then the average person who lives in the same kind of life as them. They want an adventure and they want to explore.
