Some time ago, my grandson was watching a spoof of Harry Potter on his all encompassing Ipad, which I happened to be privileged to witness by chance, on this particular occasion, and it had HP and his pals raiding the bedroom of Snape. They found his diary, which they noted "was just lying there in a locked box under his bed" ... and proceeded reading it, the text of which I don't recall, as provocative as it might have been, and then they made a new entry, which I don't recall at all, but it was juvenile in nature.
So there sits my grandson, age 6, taking it all in. He absorbs all this like a sponge. Recently I had occasion to ask him about it, and HE had to remind ME that it was HP doing the snooping, which I didn't exactly recall.
O Brave New World!
