Walking Through Walls

I laughed along with my best friend as she told her story, tears of laughter streaming down my face. We laughed for a while until I heard footsteps down the hall. I whispered goodbye, knowing I probably wouldn't see her for the rest of the night. The door swung open.
"Were you talking to someone?" My mother asked me while I looked behind her.
"Nobody, just myself," I replied as I watched my best friend disappear through the wall.
