Nicole rotated Orla's door in March 2012. Orla could now lock herself in and come out whenever she desires.
Nicole: "I'm going to rotate Orla's door. The lock will be facing Orla's room."
30 minutes later...
Nicole: "Now I removed Orla's door. Let's put it back in."
15 minutes later...
Nicole: "Alright. The lock used to face the wall over there. Now it's facing the wall in Orla's room."
