Matt and Attean are teaching absolutely necessary lessons when they spend time together. Matt helps Attean to understand White language while he received real living lessons. For example, hunting without weapons, making arrow and bow and ways to prevent get lost in forest. Both Matt and Attean teaching have vital effects to other. If there are not Attean's practical introductions, Matt can not exist in strange place. Likewise, without White's language, Indians will be hard to understand treaty, and it is really harmful to own rights. It seems strange, but I really have an essential experience from my uncle. He told me a story which named "Let's him get accident in next crossroad". It means we should not angry whenever we are in fretty cases. We should keep our minds relaxed. I always feel annoyed when I get something is not satisfied, so my uncle's attitude is my a best lesson.
