It would have been easy for Neville to guess which one of the cottage's windows belonged to Luna. A few hours after relocating herself into the new space, she had hung holly and chimes from the frame ad cracked open the glass a few inches. Not even the blistering cold of January would keep her cooped up. Not even again - and she'd ward the crack enough that the fresh air that came in was at least room temperature.
The rest of the room was totally hers as well, colors draping the walls and curtains hung from the rafters to give it a 'softer' look. If she couldn't be home, and she couldn't be at Hogwarts... at least she could be comfortable.
Of course Mrs. Longbottom thought the whole affair was a mess and on more than one occasion 'offered' to come in and 'help' her clean the place up. Luna in return, had taken to locking her door when she wasn't inside, and keeping half-an-eye on the old woman... less she get too many ideas. She was sweet, Mrs. Longbottom. Terrifying, but sweet. Luna had started to make them both tea at the end of the day, and that had garnered her a bit of a truce.
She had just started to fold and string another row of oragami cranes when the rocks began to knock on the glass. She jumped (just a bit) before realizing it wasn't all in her head. After unfolding herself from her spot on her bed she made her way to the window, and laughed at who she saw below.
