I saw a mouse outside a window last night, and it didn't look like a regular house mouse; with its big eyes, big ears, and white underbelly, it looked a helluva lot like a hantavirus-carrying deer mouse.
So not only is my house poorly insulated -- with a leaky roof, broken doors, and bad wiring on top of it -- but it's exposed to potentially life-threatening vermin, too.
When my landlord dies, I hope he comes back as a mouse and gets eaten by a cat.
