Dear Stuart, and Ralph,
I love you for what you are. I especially understand your disgust, Ralph, toward the misconceptions about mice. I am happy to live and let live. It is fine that you use our shed as a winter haven. I am even OK with your use of the small crawl-space. The larger crawl space is negotiable.
But, when you use our vacation as a time to frolic through my silverware drawer, mark the knife drawer as your own, and leave your dropping in my ice cream scoop, you have taken my hospitable, live-and-let-live attitude for granted. You have not just teetered on the very edge of the line. You have catapulted yourself over into territory that I will fight for.
Be warned, the farmer's wife has moved in. I will trap you. I will poison you. I will cut off your tails with a carving knife to reclaim the acceptable level of sanitary In my kitchen. You will be forced to retreat or die.

PS: To insure the continued existence of your genetic line and the return of the generally peacefully coexisting wife of a comedic engineer, pack your bags and return to the smallest crawlspace, the shed or the many holes in the yard.
