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(魔术师) ．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 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, Kevin
