Dear Harry Potter,

     Hi! I'm Kevin from India. I really feel lucky to write you a letter.

    Though I live far away from your world, I think we are a little alike, You are a great wizard (奇才). You

have done lots of magical things to be amazed at. Although I don't do magic. I do believe in it. Well, I'm also

a wizard at school. And I can often get As, but I am not a bookworm. I like to play jokes in class, which

sometimes make my teachers angry. I also have many friends. They often get me into and out of trouble.

No matter what has happened, we still get close together.

     Oh, I almost forget to tell you that our school is almost like yours, Hogwarts. It's a special one for

excellent students. We have modern classes and technology lessons. But when much is given, much is

expected, so I often stay up late just to finish my homework. It really makes me tired and bored.

     Luckily, I can read your stories in my free time. I feel like I know you. You have a mind of your own.

You are young, but you know how to take responsibility(责任) for your decisions. Also you think with a

clear head even in danger. What a great boy you are! How I wish I could meet you soon!

     May you have a nice time. 

                                                                                                                                Yours,
