About bully

I think bullying someone is very bad thing. But how do you think I say it can happen anytime, anywhere to you?
I have seen the situation that some of my classmates bullied a boy. The boy was fat.
One day, we changed our clothes to clean up our classroom. Boys and girls had to change their clothes in the same room. A boy said “ I saw that you ate school lunch too much. I think you can eat milk churn!” to the boy.
All of us laughed at what that boy said, not at the fat boy.
However, our homeroom teacher heard that accidentally. He shouted, “Who did say that! Come with me now!!” All of us were surprised because we could not understand why he said such a thing.
He told us that we could not understand what bullies were, and where they were. Therefore, we had to pay attention to our friends, our classmates, and people who were around us. It was us who made bullies, and it was us who eradicate bullies in the world.
I was impressed then. He taught us bullies could happen everywhere.
I have paid attention to bullies and my friends since then. I have warned my juniors not to bully.
I think bully can happen everywhere, and the most important thing is to realize it. If you do not realize it, you need to be aware of it first.
