Dear Mr.Smith，
I’m Li Hua, a student from Xinhua Middle School. I’m writing this letter to thank you for returning my schoolbag.
Last Sunday afternoon, after I played basketball with my friends on the playground, I left my schoolbag there owing to my carelessness. I was worried because my student’s ID card, cellphone, wallet and some documents were all in it, which were very important to me. Just as I was at a loss, I was informed that my schoolbag was at the school’s Lost and Found, where I knew it was you who had picked up my schoolbag and handed it in.
It’s such a great kindness that I’m extremely grateful to you.You did set a good example to us.
Yours，
Li Hua
