Parker at her Prime

I'm sitting at my desk right now, which is in the loft of our house, the staircase and Parker's bedroom door are about 6 and 9 feet behind me.  I thought Parker was downstairs watching Scooby Do, while I'm here working at my desk.  But a few minutes ago I heard her door shut, I assumed the wind had blown it, but then I heard some clicking noise, so I went to investigate.  Upon reaching for the handle, I discovered something was amiss, it was locked.  Through the door I asked "Parker, are you in there?"  "Yes, I'm going to sleep!"  Somethings not right here, so I unlocked the door to find her in her bed, wrapping something up in her blankie, under her comforter.  I ask again, she sticks to her guns, "I'm going to sleep!"  So I pull up the comforter, and pull back the blankie to discover a half eaten cookie.  The thief and liar strikes again!
