House-sitting and Paranoia

I am house-sitting for a nice lady and her husband. They own a heart shaped hot tub, three horses, two dogs, and a cat. Their house is big and has nice furniture. My cat likes it here. I sleep in a comfy bed and am absolutely paranoid. I walk quietly and lock all the doors. I have no gun and feel very vulnerable. It is hard going to sleep at night because there are noises I do not recognize. If I were a badass I would not be so scared. This sort of fear is worse than climbing scared because it is not a fear that is diminished by endangerment, like purposely taking a whipper, it is a fear based on worry and suspicion. Wish I had that .45 under my pillow. Night sights would be nice too.
