Twain was limited in expressing his thoughts by the fact that Huck Finn is a living, breathing person who is telling the story. Since the book is written in first person, Twain had to put himself in the place of a thirteen-year-old son of the town drunkard.

But other times they just lazy around; or go hawking--just hawking...when things is dull, they fuss with the parlyment; and if everybody don't go just so he whacks their heads off. But mostly they hang round the harem.'
