Dear Mary

I had seen your note as well as email address on the website for making friends, so I decided to send you this email in order to introduce myself. My name is Nha, and I am an 11th grade student. I live in Vietnam - a small country in Asia. I knew that you are from the USA, and I would love to chat in English with you as well as share many interesting information about both countries together. I am a friendly, active, and outgoing girl. Therefore, you can have a lot of fun times once you decide to be my friend. My hobbies are reading books, listening to music, traveling, and drawing pictures. My favorite books are Harry Potter, Lord of the rings, and Peter Jackson. I collect a lot of books in English, so it would be a great thing if we can exchange our books with each other. I saw that your hobbies are also listening to music and drawing, so I guess that we can have a lot of common things to talk about. Most of my pictures are about the nature and my pets, and I wonder which subjects that you like to draw. I love to travel, so maybe one day I will have a trip to USA, and I think it is wonderful to already have a friend there. I think you and I have a lot of things in common, so I hope we can become friends. Every day, I spend about an hour at night to online and check my mails. Therefore, you can text me whenever you want, and I will reply you in no time. I also enclose some of my pictures as well as my drawings, and I hope you have a fun time checking on them.

I am looking forward to hearing from you soon.

Sincerely,

Nha.

Спасибо
