A few more hours at school, with built-in time for homework and activities, is not overwhelming and there’s still time to relax and play.
And they have already spent far more then necessary being indoctrinated.
There is no time for play or relaxation in the world we have invented for children and certainly there is no freedom or independence.
By the time the child gets home at six, has dinner, had done his two hours of homework it is nine at night. Just when is it that he is suppose to play? When is he suppose to interact with his family?
It is puzzling why you would want to leave you child in a kiddie prison even a minute longer then necessary.
