Ds is doing his best to claim the right not to read. At nearly 11 he has literally never read anything he has not been forced to read; he claims himself that the last whole book he read was a Magic Key book in Yr 2 and that may well be so.
It is not that he has had poor teachers, or not been encouraged to find reading material he enjoys, or has not had access to stimulating reading material (the house is full of books, public library on the doorstep, any amount of charity shops)- he just literally dislikes the activity of reading. He is lazy and has never liked doing things that come with an initial effort.
Unfortunately, this has a knock-on effect on all other studies, so he has slipped behind even in subjects he ought to be quite good at.
I do not see this as a positive thing.
Of course it may be that one day he will see the light and try to catch up, but even then he will be at an enormous disadvantage compared to his peers who were prepared to put the work in when they were younger.
Not much comfort to me that most children would be different in his situation- this is the child I have to deal with.
Though our other child (brought up in exactly the same way) is a voracious reader- the right to read anywhere in her case would be positively anti-social: she needs to be told that other people have rights too. To be listened to, to get some help, not to feel that her reading matters more than all the rest of us.
