I don’t know how I’d deal with a woman so delicate that her nights were sleepless and full of fear if not in my presence. My wife is alone a lot when I’m traveling, and alone in motels when she travels. Different breed I guess.
That said, a home invader here, if he survived would tell a frightened tale of fleeing from vicious dogs amidst a hail of gunfire.
Put her, (or yourself) at the end of a 1/4 mile driveway, in the woods, with no neighbors, and the law is at least 1/2 hr away.
Now have someone knock on the door at 1am,, it happened.(turned out to be the law)
After that, how would your wife feel at night? (PS,, coyotes killed the dog.)
