I am the headmaster. How to write the ending of the composition?

Principal, a word that scares millions of students. I always thought that the headmaster was a fierce person, and I always thought that he (she) was "above", but I was wrong. President Yang of our school is an amiable person.

President Yang has a lot of hair. He often wears a light brown coat and black trousers. Always put your hands behind your back and have a leadership style.

Although he is fierce, he is actually the opposite.

Remember, the other day, we were reading early. It was good at first, but after watching it, people started to play, talking at sixes and sevens, and almost everyone was playing. At this time, President Yang, who was patrolling, saw him enter the classroom. Everyone immediately returned to their seats, took out their Chinese books and pretended to be reading just now. But my heart is beating faster and faster, and I'm thinking: it's over, I'm dead, and I'm sure to be scolded by the principal. I see that almost everyone's face is full of fear and tension. Those people with bad records are afraid of being recognized by President Yang, so they tell the class teacher and write instructions ... Just when we were worried, President Yang kindly said, "If you want to collect your homework, hurry up and don't collect it from your classmates." A day's plan lies in the morning, and a year's plan lies in the spring, so we should cherish the morning ... "With that, President Yang left. At that time, we all stayed, and I thought: I didn't expect President Yang to be so good!

How's it going? After listening to my introduction, do you envy me for having such a principal?
