A letter to my father was written in 500 words.

Hello! In the past ten years, you have taken good care of me and made me live a happy life. In this letter, I sincerely thank you.

Dad, do you remember? On a bright night, when I was doing my homework, suddenly, I was blocked by a difficult problem. I thought hard at that time, but it was still difficult to solve. At that moment, you came over with a kind smile and asked me which question I wouldn't. At that time, I told you that question without hesitation. You can't wait to take out your notebook, write down that question, and then think about it. In the process of your thinking, I was deeply moved by your focused expression. It was not until nine o'clock that I found that you were still seriously thinking about that problem. I didn't want to disturb you at that time, so I went to bed. Until I woke up, it was past eleven, and I found the light in your room was still on. Through the crack of the door, I saw you sometimes thinking with your head, sometimes bowing your head with a pen, and tears suddenly blurred my eyes. ......

Dad, you are not afraid of being tired for my study. This bit by bit is your concern for me, which makes me deeply realize the greatness of fatherly love. Don't worry! I will definitely repay your selfless and great fatherly love with excellent results!

I'll call it a day. Goodbye!

hope

Good health!
