[范文] Dear_Peter，I_am_writing_to_ask_whether_you_are_able_to_do_me_a_favor.
I want to have a penfriend, 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 such a penfriend, I hope I can share with her our experiences in traveling, taking care of pets, or whatever we have in common. 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. Best_regards，Li_Hua
