Dear Lisa,

I have received your letter and I feel so glad when knowing that you had passed your examinations with good marks. And thank you very much for your T-shirt. I love it! How are you today? I am still fine. I backed to school last week. And now I have to do a lot of homework that my teachers gave me yesterday. Did you go to school? Now I am preparing for my examinations. It is very hard for me but I try my best to pass the exam.

I have told you something about my own family life. How about your family life? I am really excited to hear about it.

Best wishes to you!
Your cousin
