The best schools tend to have the best teachers, not to mention parents who supervise homework, so there is less need for self-organised learning. But where a child comes from a less supportive home environment, where there are family tensions perhaps, their schoolwork can suffer. They need to be taught to think and study for themselves.
It's a tender and complicated dance, watching our parents age. We become protective in ways we never were before, and we study them with a mix of sadness and curiosity: Is this what we will be like when we are their age? We tell ourselves to be patient - just answer the same question again as if it wasn't answered a moment ago.
