I am writing to ask whether you are able to do me a favor.
Nowadays, I have been hunting for a pen pal. There are some requirements you can consider when helping me find some. Above all, I am at the age of 18 this year, my pen pal is supposed to be my peer. Furthermore, as you know, I am a boy student and finding a male is what I want. Last but not the least, I am in favor in the one sharing the same interests with me. I have a range of activities when I am free：going travelling, doing sports as well as keeping pets and so on. These hobbies enable me feel relaxed after school.
Looking forward to hearing from you!
