I Hear Noises Upstairs

I hear the distinct sounds of a muffled feminine voice, followed by some banging, something falling over, and shuffling feet. Concerned for my stepdaughter, I get up off the couch. The noises cease, but I head up the stairs to see what's going on. I walk down the hall, wondering what might be going on behind closed doors. I arrive outside her room and hear her say "shit" in a hushed tone.

I knock lightly on the door. "Sarah?" I ask, but hear no answer or further noises. I knock again, but hear nothing more. I slowly turn the door handle, opening the door.
