What is behind door number one...

Years ago Melissa used to work one on one with an autistic boy named Stephen. Whenever at Stephen's house, Melissa made it a habit of tossing her bag in the closet. One afternoon while they were working, her cell phone went off. She had it set to vibrate and their work paused as Stephen's eyes widened with the buzzing sound coming from behind the closet door. Stephen pointed and hollered to Melissa, "There's a cow in the closet! There's a COW in the CLOSET!!" Melissa had to admit that the buzzing did have a moo like quality and Stephen was very relieved when he found there was no cattle in the closet.
