pardon my french but i truly think this is a fallacy. i dont think it really sets the precedent. at least not by reading. there is already a lot of boring tasks one has to do everyday.
that is why i dont insist on reading. but dd knows the boring stuff she HAS to do - like the dishes, sweeping and other chores at home. however she does have other 'boring for her' stuff that she has to do at school that she does do.
i refuse to spoil her reading that she enjoys sooo much (even in 3rd grade she has decodable books that are a joke, though i think she has to read them only 3 times). she does them once if at all.
