I was foreign exchange student last year. My host mom emailed me first. I still have the email. I was so worrying about going to a new family that i dont know.tell about your family , where do you work , and about your children. From their first email I could tell that I would be welcome in the family when i get there. They said they were so excited about getting an exchange student to their house.I was so relieved when i read it.You should ask about her too. like her life style , what does she like to do , what does she like to eat. Because these are important to get to know each other. So your exchange student could feel happy about coming.
Something that I wont forget is; they asked my favorite color. When i first walked in to my room , it was all painted with my favorite color. So that was really cute ..
