Question

How does this quote from Huck Finn contribute to realism?
“I hadn’t had a bite to eat since yesterday, so Jim he got out some corn-dodgers and buttermilk, and pork and cabbage and greens—there ain’t nothing in the world so good when it’s cooked right—and whilst I eat my supper we talked and had a good time. . . .We said there warn’t no home like a raft, after all. Other places do seem so cramped up and smothery, but a raft don’t. You feel mighty free and easy and comfortable on a raft.”
