Haha, about my parents, let me say that:
*I have no idea of whether my dad likes it or not, 'cause he's always mocking about it (which I HATE

) in the movies and all, but on the other hand, he had read every one of my books (which I HATE too, 'cause I read them the most carefully I could, trying not to open them too much, and he took them and opened them in such a way! that I nearly hide them)
*my mum likes the movies, and she really makes a huge effort to catch up with them and understand the plot, but sometimes she lose track and then I have to explain it, and she will never read the books 'cause she says she's too busy as to read such a long serie (she tried once, though, with PoA)
*my sister likes a bit the movies, but she doesn't undestand
anything of the plot and I don't bother to explain her either because I know she'll exasperate me, and I think she doesn't want me to explain too much.
The most annoying is that sometimes they say things that have nothing to do because they don't understand, or something. Grr, that drives me mad.
