That is very true. It feels nice to be a fun teacher whom students can relate with as their friend but we need to establish our authority as 'second parents.' This is one of the effective classroom management skill that helps them recognize the need for order and discipline. It is very difficult to teach in a classroom that is in disarray. But you are also on point when you said that authority does not mean being a ruler but just someone who can competently manage his class and someone whom the students can trust. great piece.
