Dear Hanna,
I was very excited when I opened your letter. How are you? Hope you're well. I'm glad that hearing your favorite subjects are history and art. I have studied so many interesting subjects at school. In my opinion, they are so good and helpful for the students to learn and practice. For example, we've learned English at the school. That means we can understand and communicate with the foreigners in the future. If I have a chance, I want to study Japanese as a subject at school. You know, I really like watching Anime and like Japanese tranditions.
Write me when you can.
Your friend
