She left me for the gym

So my flatmate left for the gym tonight. While she was gone I proceeded to move a large Macy's shopping bag from the room with the comfy napping spot to the door she always leaves me from. She's been watching me investigate and nap inside this bag for a few days now. She gets confused easily so I knew moving the bag would throw her for a loop. She was so confuddled when she walked in the door. It was great. "What have we been doing Blanca?!" She'll never figure out how I pulled it off!
