Possibly because you just told me my mother sent you garters and it's either a prank or mum has gone barking mad. Someone is pulling someone's legs somewhere and mum never had that much of a sense of humour.
And you can tell her how awsome it was all you want as long as you don't mention what I said. Your aunt has one hell of a temper, in case you didn't know that already.
I'll let Victoire know you said that, and you can trust me on the Quidditch part, I'll make sure it happens.
