Dear Stan,
Thanks for your recent letter. I was really pleased to hear from you that you want to have a pet.
In my opinion,it is a very good idea and your life will be more interesting if you have a pet. I think you should get a dog because dogs are best friends for everyone. It will be better if you get it from a pet shop. By the way,i also have a pet. It is a little puppy. I walk with it two times a day and feed it with a special healthy food for dogs.
Well,that's all for now. Do write back soon.
All the best.
