When should one reprimand?
Our teacher (Mr. Sonntag) has decided that we will get a reprimand for a few things
For example, if we call him mister/Mr Sunday or we talk in class without being asked (the last one is not properly enforced)
Do you think it's fair?
Well, if you behave like a first-grader, you'll be punished like a first-grader. There's nothing more to say.
