The class was very noisy; some of the students were talking to each other and some were on their phone or doing homework.

Additionally, there were no teachers to discipline them since it was announced that your professor will be absent this week.

Suddenly, a tall and charismatic man walked in the room, holding a textbook, his presence silencing the class.

"Good morning students, call me sir Redson. I'll be your substitute teacher for the week. Now, get your textbooks."
