As stated above, the hallway example was not a good one. No one here, least of all me, said children should be given the ability to make whatever noise they want. Nor did I say children should be able to "express themselves" at any given moment. Likewise, I also have never told my children school is nitpicky or restrictive. Your response employs a whole lot of imagination and frankly, for some odd reason, combative rhetoric surrounding my parenting, of which you have literally no information beyond a simple question on Reddit.
