My stair-case is way too old and creaky to safely and quietly travel down, so I would have to stay upstairs. I'd hide in the closet with the nearest weapon I could find. I have a guitar opposite my bed, iron bar beside my bed, three wall-hanger swords in my closet. Three to four knives on my desk (second choice after the iron bar.) Computer monitor. A few airsoft guns, the stock would cause some head trauma if hit in the head x number of times, the primary use of them is ultimately useless. Rack to hang clothes in the closet, rack to hang pants/shirts in my bathroom, the lid to the toilet chamber, T.V. remotes, printer, guns when I have them.
I wouldn't try to kill, but I wouldn't hold back. Yay for the Castle Doctrine.
