英语故事:Thank-you note 感谢信

【英文原文】

Thank-you note——感谢信

The son of a friend graduated from high school, so I sent a card to congratulate him. I enclosed money and scribbled some words of wisdom inside. He sent me a note back saying, "Thank you for the gift. Also thank you for the advice. My mom always told me that you are full of it."
