I am writing to ask for whether you are able to do me a favor. I want to have a pen pal, hopefully a girl in the early twenties, and with interests similarly to mine. In my mind, he is someone interesting in traveling, swimming, and playing table tennis. Beside, it will be better for her to have a pet dog as I have been keeping one at home for some time. With such pen pal, I hope I can share with her my experiences in traveling, taking care of pets, or whichever we have in common. I believed I will improve my English by doing so and learning more about her country. I am looking forward to hearing from you soon.
