Marco’s Eventful Night

Awakened by Buddy’s thunderous barking, I looked out my window and was surprised to see my gigantic dog barking at the back door. Buddy preferred being outdoors and never barked to come inside, so I became alarmed. He was barking at something inside the house! My heart sank, and I slowly crept down the stairs to let Buddy inside.

I paused when I heard soft movement coming from the kitchen. My heart sank even further as I realized I had to go through the kitchen to let Buddy in. As I crouched on the floor to peek around the corner, I caught a glimpse of the striped tail of a raccoon digging in a box of crackers. Startled by my loud sigh, he quickly jumped on the counter and out the open window. I leaped across the kitchen to close it and watched as the intruder scampered from the yard.
