Goodness, you have been unlucky as I have never seen any who do any such thing in 15 years. Parents yes, but not teachers. I have that too these days. Amuses me no end, but is purely down to being known in the school and to experience and age. Except that classrooms are not, and cannot be, fully democratic. You are the teacher and sometimes you have to issue instructions for children to comply with purely 'because you say so'. And then you have to enforce that. This does not mean that you don't respect them, but that you are in charge.
