Today I am so tired!
　　I donot know why,but just feel something wrong with me.
　　Just now,I recieve a letter from my brother feng.And I am so happy.
　　He is my netfriend and now he was studying in USA.
　　He encourage me to study harder.
　　I like to chat with him through internet,because he is a very nice guy.
