Dear Kate,
Thank you for your letter! Nice to hear from you again.
In your previous letter you asked me about pets. Well, I think that keeping pets is popular everywhere. Talking about my country, we don't have any exotic ones here, only cats or dogs. And I think it's fine because I don't approve keeping wild animals at home. They should live in their natural habitat. Anyway, I don't have any pets. I hope one day I will adopt a dog.
My mom just called me for dinner, I have to finish my letter now. Write back soon.
Best wishes,
Name
