We keep Elsie tied up all the time now. Some days are better than others. We only have to tape over her mouth on the worst days, when she does nothing but scream and try to bite us. On the good days you can talk to her, small talk, nothing major. Say anything about zombies and a good day quickly becomes a bad day.
I can see how watching your dead father eat your mother alive could drive a teenager out of her mind. I don’t blame her. It’s amazing we’re not all like she is after what we’ve seen.
