You're a cat.

Minerva was working at her desk, her nine little ones resting in their cribs in the corner of her office. Two weeks after their birth they still slept most of the time.

"Minerva?"

"Is there a problem, Severus?"

"Someone is banging on your gargoyle."

"I see."

She got up and opened the door.

"Dilys watch the baby for me, will you?"

"Of course my dear"

She climbed down the stairs and opened the passage behind the gargoyle. Mrs Flitwick stood in front of her.

"I want to see my grandchildren."

Minerva kept a neutral face.

"Follow me."

"Your stupid gargoyle wouldn't let me in without password."

"That's her point."

"I told it I was your mother in law. It didn't believe me."

"Anyone could have said that. Now to avoid any further disagreement, my password's Desdemona. And hush most of them are asleep."

"How many did you have?"

"Nine. Filius didn't tell you?"

"No. You only had nine?" She seemed genuinely surprised, "Goblin usually have 15 to 20 children at the same time."

"I thought Filius hadn't any siblings…?"

"His father was a wizard."

"I'm a witch."

"You're a cat."

She sighed as they neared the cribs.

"Is that Silk?" Mrs Flitwick pointed the sheets.

"Yes… I'm rather fond of Silk" the not-so-young mother said.

"But that's a lot more expensive than Cotton."

"Well… I can afford that."

"That's beside the point."

"Then I fail to see your point."

"It's very simple: why did you buy Silk when you could buy Cotton?"

"The answer is just as simple: I like Silk better than Cotton"

"But Silk is more expensive!"

A cry stopped what promised to be quite a boring argument. Minerva took Celarem from his crib and lulled him. Mrs Flitwick jumped on her son's pile of book and looked inside the two little cribs.

"Are they all black haired?"

"Yes. Both I and Filius are."

"What colour are their eyes?"

"Greenish blue for all of them"

Minerva put the now asleep Celarem back with his brother. Her Mother in law jumped down.

"Great. Take care of them and see you next year."

She leaved at once. Minerva blinked.

"Goblins are a bit weird…" She said to no one in particular.

"My mother wasn't that bad." Albus commented.

"Yes. And there is a very good reason to that."

"And which one is it?"

"She had no idea we were married and even less that we had twins."

She smiled to her babies once more and went back to work.
