You see the only way that you can really discipline them  is when you have a school where  the rules have been very, very strict from the moment that they went into that school  and they have had their noses held to the grindstone  with work up to their brows  and they just don't think of being tiresome  and anybody who is tiresome is pulled out and put in a special room on their own, called a sin bin  an which is rather boring  and made to work even  harder!
