how are huck and buck similar

well they both live in little back woods cabin with their families, even though huck's was only with his father. other than the obvious, such as their age and height, they are both slightly under educated children. for example neither of them speak perfect english and they seem to live in their own world. this could just be because of their age or their lack of education, but they don't seem to see things in a broad picture. for example when huck asks buck what a feud is, buck tells him that it is a long lasting fight between his family and their rival family. he tells him this instead of defining the word, and huck tends to do this also.
