A MEMORY

When I was 20 years old. I wanted to become a teacher in the future, so that I often helped children who were younger than me with homework. One day, when I have sat on the bench in front of my house. I saw Nhi. She is seven years old and she my good friend in my next-door neighbour. I came to her and asked " What are you doing?" She said: " I'm doing a math, but it is very difficult." She asked for some help from me.
I was reading a question and that was not a difficult for me to do. It said "9-4=?". I have thought an easy way to explain for her to understand, and I said," Every morning, your mother gave you $9, and you bought a sandwich to eat for $4. How much money did you still have left?" During the time to explained I have used to my nine fingers for an example. She has thought a moment and said that:" Every morning, My mother made a noodle soup for a breakfast for me, but she has never give me a money. How can I give you an answer??? It is extremely hard". She made me laugh out loud. However, I understood her because she told the truth she was still childish. She is very lovely.
Now, she has became an adult. I looking forward to see her again in the future when I go back to my country.
