Is Shakespeare influential? And if so, why? I suspect he's only influential because they made him look influential, as it always happens way too often in too many other cases.
Are some important authors almost unknown? And if so, why? I suspect they are not influential because they made them look not important, as it always happens way too often in too many other cases.
Answer to your question:
What should a reading heritage be for pupils in 2015?
There's no answer to that question, because it's a stupid question. Pupils, irisis, eyelashes, students, or whatever you want to call them, are NOT in school to read stupid books. I thought that was clear enough. Everyone knows school is meant to be a place where people play with their cellphones, play tricks on the teachers, and smoke weed in the bathroom. Who the hell reads books anymore in school, in 2015?
