Tow teachers

I met two excellent but strict teachers this semester. One of the teachers, Bill is in the writing class. I was impressed by his look. He has a strong body and a kindly face with beard. I thought he will be very nice as the teacher before. However, the fact is that I was wrong. But I like the way he was going to teach us. The other one is a new teacher, he retired from the other university. He had a very special accent. Both of them have their own rules and they respect rules very much. They emphasized that everyone had to follow those rules or we might fail in classes. I was excited and anxiety for these two classes.
