"Taking it."

"That doesn't sound like a great idea."

Miranda laughs. "Taking it and then telling Karen that I live on a houseboat on the moon with six pet dragons."

"Oh? Wow, congratulations. On either having mastered Occlumency really fast or having figured out how to tame dragons."

Helpless giggling. "I'd be more impressed at the moon thing, really!"

"Both seem pretty impressive! How do you get to the Moon, is it a long flight?"

"Oh, yeah, takes ages."

"Congratulations. ...depending how many people you've told, you might not want that widely known just yet..."

"Karen knows, Professor Mousebane knows, Mum knew I was going to try and will ask how it went, and honestly of all the things that might make being a perfect Occlumens suspicious 'not telling people about it' seems high on the list..."

"Fair enough. Going to try Legilimency?"

"Uh, no."

"I don't get the impression it can be used accidentally."

"I'd need a way to test if I had it and I'd need a reason to expect to ever want it."

"Fair enough."

"Besides, lots else to do."

"You don't say!"

"I do say! Do you think Aaron would enjoy knowing what I spent his Christmas present on?"

"I bet he would!"

So the next time Miranda is over at the Ravenclaw table during lunchtime she tells him.

"Cool! What'd you want it for?"

"Testing my Occlumency."

"Huh. Did it work?"

"The Veritaserum or my Occlumency?"

"Your Occlumency."

"It works."
