I wasn't on night duty but went to check on my girls anyway because they'd been misbehaving that day. I went to their room to find them missing, I knew exactally where they'd be so went to one of the other rooms and banged on the door. I gave them the riot act and sent them back to their room and when everything had quietened down the councellor that was on night duty popped her head around the corner. She'd been sat on the floor reading a book and a) didn't know they were in there and b) only came to see what was happening after I'd sorted it out. The room they were in belonged to her group which made it even worse in my opinion.
She was pretty much useless all summer.
