Bugger Moaning Myrtle

I understand that ghosts are part of our way of life here at Hogwarts. I do. I like the terror that the Bloody Baron inspires in the hearts of first years. I am continuously entertained by the pranks that Peeves plays on Hufflepuffs. I enjoy blaming pranks that I play on Hufflepuffs on Peeves. But I have had it up to my eyes with Moaning Myrtle!

I understand that it's unfortunate to be killed in a toilet. I understand, furthermore, that being killed by a creature controlled by the heir of Slytherin might prejudice one against future members of that house. What I do not understand is why she feels the appropriate response is to remove all the toilet roll whenever I come in there!
