Diary for Bai Yueguang

Do you know that I promised you that I would let you copy math problems for the rest of your life, but I went back on my promise. Do you know that I am afraid that you will see me riding an old tricycle every time after school. Do you know that in summer you wear a white shirt and become a quiet corner in my heart? Did you know that every Sunday, you walk two or three kilometers to your doorstep?
