It is great to have pen pals. In my opinion, friendship is among the meaningful relations in our life. Many of my friends have pen pals and they correspond regularly. A friend of mine once got a letter from the school mailbox and told me a lot of interesting things about her pen pal. That made me excited and I was eager to have one. Therefore, I got online and did some chatting. I was lucky to get to know a very nice Australian girl. Her name's Jenny. She and I are the same age and we have a lot of things in common.

Although my English was not very good at first, we were able to understand each other quite well. My English has improved a lot. Jenny has never been to Viet Nam. However, she thinks well of our country and our people. When she comes to Viet Nam, I will take her to some interesting places, especially our World Heritage Sites, such as Ha Long Bay, Hoi An Ancient Town, My- Son Tower. Through her mail, she tells me about her country. Thanks to Jenny, I know more and more about Australia. I hope to be an exchange student in Australia some day and we will be able to meet.
