If I'm suspicious it is because, like I said, I've never noticed you saying anything about Slytherins before now. It just seems rather sudden and ill-timed, doesn't it? Given that we're all trying to present our best selves to our visitors.

I don't think it would have been so much trouble to have said "Despite what you may have been told about the squid" instead of "No matter what the Slytherins told you" - as if we're all sitting round, cackling at the thought of French and Eastern European people being drowned in the lake.

I mean, I suppose that you didn't mean it like that exactly, but like you yourself said, things in the journals can be mis-read, if one isn't careful about how they write.
