Freedom of Students

That's a good question you have there and if I may share my thought on that I guess it depends.I said that because I have been a student years back and during my time students were different.It also depends if you are in elementary, high school or in college.if you are a student for elementary I guess most of the time the teacher will ask students to behave and to listen ., greet visitors politely etc., if you are high school there are rules that should be followed and if someone disobey that there will be punishment. for college there's no need for some rules or regulations in the classroom mainly because college students are already grown ups as well.
