Dear Max,
Thanks for your letter. It was great to hear from you. I'm sorry I didn't write earlier but I was very busy studying.
In your letter you asked me if I help my parents around the house. Of course, I have household chores. I have to walk the dog, wash up and clean my room. Sometimes I can not do the chores because of my studying and then I ask my parents to do them for me or to put them off.
Now it's my turn to ask you some questions. What do you do at your free time? Do you like snowboarding? Do you have any pet?
I've got to go now as I have to do my homework. Keep in touch!
Take care,
John
