Dear ...,
Thank you for your letter!
In your letter, you asked me about my shopping with my parents. I always go shopping with them, they are always give me helpful advice. I really fell comfortable in big supermarkets, because where i can find a lot of different things, like clothes,books,shoes,and even food. I really like to buying books. Because, i like to read. To my mind, books play an important part in our life.
A lot of love.
