OK, I just thought of this last night when I was waiting to drop off 
to sleep; Given the Weasley parents' attitudes towards Muggles and 
Muggle culture (not to mention the number of kids underfoot!), why 
didn't the Weasleys send their kids to a Muggle primary school?

 (Or, if they have, how did Ron come out of it still not knowing how 
to use a telephone?)
