下面是大明写给他朋友Tom的信，信中描述了他的烦恼。请你以他的朋友Tom的身份，给他写一封信80词

Dear Daming,
I know your problem. You’ve made two mistakes. First, you used your classmate’s pen without her permission. Second, when you broke the pen, you didn’t tell her the truth. Yes, you must tell her immediately. If you tell her the truth, perhaps she’ll be angry with you, but at least you’ll prove you are honest.
Then I think you should offer to pay. You can use your pocket money to buy a new pen for her. She will realize that you’re truly sorry.
I hope the advice can help you. I’m sure you will make up with her soon.
Yours,
Tom
