Write a letter to your friend about your family

Dear friend! How are you doing? How are you? How is the school year? I decided to write you about my family. We are a family of three, me, mum, dad and my older brother. We are a typical Russian family. Get along very well with each other. And with my brother, we are just crazy. And fight, and swear, and rage , but don't stop loving each other. Even though there's a big age difference, but it did not stop us to find common interests, for example in music. Here and so. 
Please in your response tell me about your family. Your friend.
