Back when Fergie-Dog lived with me, she had the strange habit of sleeping with her eyes wide open. She looked pretty dead when she did this. Usually when I came home from work, my key in the lock would wake her up. On rare occasions when I came home, she would fail to wake up. I would gasp thinking she was dead and rush over to her. At that point she would wake up surprised. For some reason it took several instances of this happening before I learned not to assume she was dead. Now it's kind of a fond memory, but, damn, that takes a lot out of you.
