The important thing isn't the house. It's the ability to make it. You carry that in your brains and in your hands, wherever you go... It's one thing to carry your life wherever you go. Another thing to always go looking for it somewhere else.
What scares me is what scares you. We're all afraid of the same things. That's why horror is such a powerful genre. All you have to do is ask yourself what frightens you and you'll know what frightens me.
