Dear Peter, I’m writing to ask whether you are able to do me a favor. I want to have a pen friend, hopefully a girl in her early twenties, and with interests similar to mine. In my mind, she is someone who is interested in traveling, swimming, and playing table tennis. Besides, it would be better for her to have a pet dog as I have kept one at home for some time. With so a pen friend, I think I can share with her our traveling experiences, taking care of pets, or whatever we. And I believe I will improve my English by doing so and learn more about her country. I look forward to hearing from you soon.
