Given the question "What kind of families can be possibly chosen as home-stay families?" and the answer "Close to the school.", write a conversation that might have happened.
A:
M: How are your home-stay families chosen?W: We have special requirements that our families must meet before they are invited to have our international students. We require that the family lies live within a reasonable distance of the school, have enough living space for the student, and live in a clean, safe and comfortable area. We also work with families who enjoy having international students. We try to match each student with a family as best we can.M: If I stay with a home-stay family, what should I expect?W: The family will treat you as a guest, and you will be expected to obey house rules. All families provide a single or shared room and a choice of meals. In most cases, students will be expected to share the bathroom. Experiences has shown us that living with a family is the most interesting and effective way to learn the language. Remember, your home-stay family will have different customs and habits from what perhaps you are used to. Meals will be prepared by the family. All home-stay families are within 30 minutes, travelling time of the school. The smaller the city, the less time it takes to reach the school.
