Написать письмо! your friend is going to the usa to stay for a year in a host family with 5 children. as she has no siblings, she is afraid of the problems than may arise.

Hi, friend! how are you?
don’t worry about your host family! i think they will be kind to you. i know that 5 siblings at first seems strange to you. however, i’m sure that they will love you very much. i will tell you about my experience. i’ve been to another country and i was in a host family. they are from the philippines. they were really nice to me. they had 2 children. i was playing with them everyday. i felt like they became my second family. i didn’t have any problem with my host family! they always helped me if i have any questions or problems. that’s why you shouldn’t be afraid of that. your host family will treat you as a member of their family. this is a purpose of a host family in another country.
