Characters: Ron Weasley + Hermione Granger
Theme: "Rawr"

Hermione is standing in their bedroom, her eyes skimming the titles of the books lining the bookshelves. Or Ron assumes she's reading the titles; he's in the doorway and therefore cannot see her face. More importantly, she cannot see him.
There's only one thing to do: he creeps across the room and growls "Rawr" in her ear.

She jumps, but he's the one who ends up on the floor, his arms and legs bound in a spell.
For future reference, Ron tells himself, as Hermione collapses into giggles beside him, do not forget that your girlfriend is a witch.


A/N: For LifeOfBreeze, who suggested the prompt "rawr".
