Sample Letter 1: My Favorite Subject Is Biology

Dear Nishchay,
I hope you are doing well. School has become quite interesting lately, especially because we have started some new lessons in my favorite subject, biology. I thought I would tell you why I enjoy it so much.
Biology interests me because it helps me understand living things. I especially enjoy learning about the human body, plants, cells, and animals. Recently, we studied how the heart works, and I was surprised by how much it does every minute without us even thinking about it.
The practical classes are my favorite part. Looking at plant cells under a microscope makes the lesson feel real instead of something I have only read in a textbook.
Studying biology has also made me more curious about nature and health. I often find myself asking questions about things I see around me.
Which subject do you enjoy most at school? Write back and tell me what makes it interesting to you.
Take care!
Your loving friend,
Mithlesh
Sample Letter 2: My Favorite Subject Is Mathematics

Dear Nishchay,
You will probably laugh when I tell you this, but mathematics has become the class I look forward to most. I know not everyone enjoys numbers, but solving a difficult problem gives me a real sense of achievement.
What I like about mathematics is that every problem feels like a small puzzle. At first, the answer may seem difficult to find. But once I understand the method and work through the steps, everything starts to make sense.
Geometry is especially interesting to me. I enjoy working with shapes, angles, and measurements. Our teacher sometimes gives us challenging problems to solve in groups, and those activities make the class even more enjoyable.
Math has also taught me not to give up quickly. If my first method does not work, I try another one until I find the answer.
Do you still enjoy English the most, or has another subject become your favorite? Let me know when you write back.
Best wishes,
Mithlesh
Sample Letter 3: My Favorite Subject Is English

Dear Nishchay,
Guess which class I have started enjoying the most this year? It is English! I used to think of it as just another school subject, but now I enjoy it for many different reasons.
Reading stories is probably my favorite part. I like meeting new characters and imagining the places described in a story. I have also started keeping a small notebook for new words that I discover while reading.
Writing is becoming more enjoyable too. Last week, our teacher asked us to write a short story. Creating my own characters was challenging, but I had a lot of fun doing it.
English is useful outside the classroom as well. It helps me understand books, websites, movies, and conversations. I still make mistakes, of course, but I can see that I am improving.
What is your favorite subject these days? Tell me all about it in your next letter.
See you soon!
Your friend,
Mithlesh
Sample Letter 4: My Favorite Subject Is History
78, Shanti Nagar
Jaipur – 302001

Dear Nishchay,
Yesterday, our history teacher told us a story about an event we were studying, and the whole class became completely quiet. It reminded me why history is my favorite subject.
For me, history is much more than memorizing dates. I enjoy discovering how people lived in the past, the decisions they made, and how those decisions changed the world.
I especially like learning about ancient civilizations. Seeing pictures of old buildings, tools, coins, and monuments makes me wonder what everyday life was like hundreds or even thousands of years ago.
History also helps me understand why many things in the world are the way they are today. That connection between the past and present is what makes the subject so interesting to me.
I remember that you used to enjoy science. Is it still your favorite subject? Write back when you have time and tell me.
Warm wishes,
Mithlesh
How to Write a Letter to Your Best Friend About Your Best Subject
Writing about your favorite subject is easier when you focus on your own experience instead of simply describing the subject. Your friend will want to know what you enjoy about it and why it matters to you.
Start with a friendly greeting and introduce your favorite subject naturally. Then explain why you like it, mention one or two topics or classroom activities you enjoy, and describe how the subject helps or interests you.
A simple structure can look like this:
- Opening: Greet your friend and introduce the topic.
- Favorite subject: Clearly say which subject you enjoy most.
- Reason: Explain why you like studying it.
- Personal example: Mention a lesson, activity, experiment, story, or topic you enjoyed.
- Usefulness: Explain what the subject teaches you or how it helps you.
- Closing: Ask about your friend’s favorite subject and end warmly.
For example, instead of only writing “Biology is my favorite subject because it is interesting,” make it personal: “I enjoy biology because our practical classes let me observe things I usually only see in textbooks.”
The goal is to make your letter sound like you are actually talking to a friend, not copying an answer from a textbook.
