I'm glad to receive the letter from you. As for the matter you mentioned in the letter, I think you'd better not keep a pet, because you will need to spend a lot of time on it. It is an expensive purchase because you need to buy food and other daily necessities for it, as well as having medical treatment.You cannot bring it to school with you, and it is important for you to do your homework. You don't have the time to play with your pet and take good care of it.
