Life is essentially a cheat and its conditions are those of defeat; the redeeming things are not happiness and pleasure but the deeper satisfactions that come out of struggle.
When I see something I like, that's all that counts. What they use, how they get there, I never bother them.
I remind everyone: Whether you school them at home or send them to school, you as a parent have the responsibility to make sure they learn and behave. Teachers and principals may help, but parents are the ones who must accept responsibility.
