10 rules for a class

You know, I work as a caretaker of a school. Last Tuesday, while I was going around cleaning up the classrooms, I saw a poster saying this:

10 rules
1. Go in the classroom smiling
2. Greet the teacher standing up and smiling
3. Take the lesson smiling
4. Be quiet during the explanation
5. Don’t yawn in front of the teacher, but turn yourself or hide under the desk
6. Raise always the hand when you need to ask something and wait for the end of the phrase of the teacher
7. Don’t contest without reason the assigned mark; if you want an explanation, you must say “professor, I know I didn’t apply myself and you are always right, but could you be so kind to explain me my errors?” (always with the smile)
8. You can’t cry in the classroom, so you have to cry in the bathroom and then return in smiling.
9. Don’t produce acoustic, atmospheric and water pollution
10. Greet the professor when he is going out, standing up sadly and with a reverence bow


I like when teens take the rules in this way.
