My room has all of my personal items, I am ready if someone wants to take my things, they can have what they want, as long as they don't come in my bedroom. Nothing worth me getting killed/shot/hurt over outside of my bedroom. My bedroom is safe, my daily ccw's are on my dresser and ready to go.
I think you are safest in your room, don't roam around your house because someone could be hiding and jump you, or sneak up on you. House phone + cell phone are on my dresser also. It also proves to courts that you are in defense mode and didn't go and search out your invader. If he comes in thats his problem. I don't want to leave my room and get owned, if my door moves I know where the person is. My dog is 14 years old and is pretty much out of the question of barking, he is pretty subdued around people now.
