Pupils have reasons for being bad

I want to be a Secondary School teacher in the future.

A teacher's job is very exciting, isn't it? But I know that being a teacher is very difficult. For example, some students like laughing and talking during lessons.

It is very hard to make them obey you and like you. I am a student too, and I do not like boring lessons.

Some teachers are good, but they do not know how to teach, so they make the lessons very boring.

There are also some naughty students in the class. They do not obey the teacher and are very impolite, so teachers get angry with them.

At first, I thought that if I were a teacher, I would not like these pupils. But after I read a book, I changed my mind.
