What is Misbehaviour?

I believe misbehaving has to do with breaking the rules, but I also feel that the context in which one "misbehaves" may not be the same in every situation. For instance in class we talked about how some teachers feel its inappropriate to sit on their desks, while others see nothing wrong with it. In this situation one teacher perceives this as misbehaving, while the other teacher see's no problem with it. I feel there are very clear cut examples of inappropriate behaviour, ie. hitting, swearing, hurting other students, but there are examples of misbehaviour that may be more subjective. For example, speaking loudly in a library would be considered a form on misbehaviour whereas speaking loudly during class would be seen as normal. I feel like the term misbehaviour has a lot to do with the social norms and the context of a situation and the responsibility lies on us to figure out when it is okay to behave in a certain way and when it is inappropriate or against the rules.
