We don't have a gun in the house, so I would either grab a kitchen knife or a frying pan (I should get a baseball bat). I would make sure it wasn't Mrs. Bee or someone I knew, and then I would hit them with everything I've got. I probably wouldn't have killed an intruder when I lived alone, but now I would have no such qualms.

If someone broke into your house, what would you use to defend yourself and your family?
