I'm already feeling a bit nervous. My normally loyal sidekick Daisy, a border collie, has been acting weird all morning. She keeps pacing back and forth and glancing at me like she's possessed. Earlier she snarled at me when I was in the kitchen making a peanut butter and jelly sandwich. I'm not sure what I should do. Right now she's standing and staring blankly into the corner. What is she doing? It's creeping me out.
