Three things that make you upset

I have some dissatisfaction toward how to lead classes of the English teacher. Because the reason is the progress of the class is slow. The reason is class contents or a rest is not interesting one more. My the second dissatisfaction is one's person who does not take responsibility for having said. Because the reason is because it is terrible contents to teach are different every day, and it is puzzled. The third dissatisfaction is an I'll-mannered person by the trains. Because I sit in the ground not a chair, and the reason is because it eats rice.
