Dear K Wilai Panicha
Thank you for your introduction letter. I believe that you are able to communicate with your host family as well, even though there are some items found errors, but not much. While your information given is not covers all the information required, i.e. you lost your family information and what the host family can expect from you, so that, you should pay more attention and concentrate at the instruction as well as more practice on English writing as well.
