Things haven't changed MM. My primary school teacher daughter says it's worse now than ever. Quite disgraceful. But when this is pointed out to parents all she gets is verbal abuse (apparently it's her job to wipe their arses!).
No one should have to put up with that but she does. Why? .... because she believes every child has potential to make a contribution to our society, irrespective of how unprepared they are when they attend.
