What bothers Bruce about being with the Motilones?

Many things bother Bruce about being with the Motilones. He is depressed because he doesn't have much to do. He is also bored. His Bible reading has become stale. He has been in South America for three years, and he does not have any converts. He is disgusted with the lack of sanitation, including the way the Motilone defecate right outside the home and throw their garbage there also. The language is giving him difficulties and he is not sure how long it will take to learn to communicate.
