Run to the bathroom

Anna didn't know exactly how long but she knew there wasn't much time left in class. She walked as quietly as she could to the nearest bathroom. When she got there she noticed one of the stalls were occupied. So she ran to the closet open one and locked the door. She sat down on the toilet lid and jumped a little at the shock of how cold it was on her nether region. She started to calm down. Just as she was slightly relaxed she heard the person in the other stall say "hey can I get some toilet roll there's none in here". Anna froze. She didn't know what to do. If she ignored them maybe they'd think nobody was here. That was unlikely though. But if she talked to her, she might wait until Anna comes out to Thank her personally...
