"Because you know me?" he answered, knowing that he did nothing to hide how he felt about people doing stupid things. If those people were usually Gryffindors, it wasn't his fault. "And really, if they can get inside this house, then it's my own bloody fault for not casting enough spells to stop them." And he would do his best to stop them and anyone else that could come.
"Right, but there are four dormitories. When you consider two have passwords and one isn't used, you're still left with the Hufflepuffs. We should check with Savannah to see if they have a password, just to satisfy our curiosity." In the end, it wasn't that important and they basically agreed on the important things, like the need for security. "I think it's the people who are here that make the difference. Lots of Potters, for example and he's paranoid. I'm assuming his kids are too, although I might be wrong. Theo would probably have some strange spell that would talk you to death," he said, chuckling.
He liked the idea of a library just for them. "I'll have to work on the lighting. That's the most important aspect for the library. And couches, but I think we have enough couches to seat everyone here a few times over." He scrunched his nose. "Maybe we can put the potion room on the top level of the public side, completely isolated from everything else. No worries about fumes getting anywhere. Or we could put it upstairs, move the dining room here and this room a floor down. It would leave us with two empty rooms here, but we can leave those for anything that comes up later and we concentrate our lives on this side of the house. We could even have additional protection spells on this side that we wouldn't have on the public side." He frowned. "How did you not kill each other in such a small house? We have six floors with just the four of us. Three once Sirius left."
