While living in Chuuk, you will essentially be "adopted" by your sponsor's family. So, you should treat your sponsor like you would treat your own parents (or at least like close friends). And, likewise, you should treat their children like you would treat your own brothers and sisters. This experience often leads to friendships that can last for years and years. Living with your sponsor will give you a very close look at Chuukese culture.
Your sponsor's family is responsible for providing you with housing and food. They will be going to a lot of trouble to make you as comfortable as possible --- even though you may not be aware of this. You will most likely sleep in a room of your own in their home although it is possible that another arrangement --- like a small cottage adjacent to the home --- might be made. Concerning food, you can be sure that you will always get the best of what is available --- even though this might not be very much compared to what you are used to. Your sponsor will make a serious effort to feed you according to an American type schedule (breakfast, lunch, and supper) even though meals do not usually occur according to our schedule in Chuuk. Sometimes extended family or neighbors will help out with meal preparation.
You should always remember that, as a member of your sponsor's family, you should help out to the best of your ability with routine chores that might come up. For men, this may involve assisting with manual work; for women, this may involve cooking or taking care of children. There is always something to be done.
However, don't be misled into thinking that island people are all work and no play. This is definitely not the case. People are very laid back and take life easy. However, everyone has a job to do and you should carry your share of the load. In spite of the fact that you will have spent a good deal of money to get to Chuuk and will be donating your time to assisting in the schools, you should not expect to be treated like a tourist. Again, you will simply be a member of the family you are staying with.
Your sponsor is required to take you back and forth to Weno at least once per month in case you would like to go to the "big city" occasionally for supplies or, perhaps, to rendezvous with Interns at schools on other islands.
