Hi my dearest daddy,

　　I am writing to you for help which I have come to a desperate need. You know I always want to be healthy and in geat shape, so I can pay more attention to teachers instruction. Yesterday, I went to library and read some books about jogging. I think I need a good jogging shoes for my exercise. I believe a strong body can enhance my study as described by our textbook.

　　I have found a cheap price of a pair of jogging shoes which cost only $500 nearby school. Daddy, you will help me buy this pair, wont you? The on sale may not last for long. Please send money as soon as possible, so I can start my jogging right away. I know you will fulfill my dream and expect my endeavor. I promise I will do my best on my study and exercise. Thank you for your consideration. Take care and wish you happiness.

　　Yours beloved son.
