He held as still and quiet as possible, listening as whoever it was came into the room. His mind suddenly started filling with all the things that could happen if he were caught. They'd be angry, wouldn't they, finding some strange kid wandering around in their house. Breaking and entering, wasn't that what they called it? They wouldn't believe Peter when he told them he didn't know how he'd gotten into the house. Uncle Neil was going to be furious with him.
But he'd hidden in closets from worse things before. He just had to keep quiet and not move and hope they hadn't heard him hiding away. He would be safe here. He could just wait there until they left again, and when all was quiet he would sneak out again and get out of the house before someone caught him.
Unfortunately, to Peter's dismay, the hiding place wasn't as safe as he'd hoped. He flinched and gasped when the door flew open, shrinking back among the hanging clothes. Even seeing that the girl seemed just as spooked as he was didn't ease his mind much. "I'm sorry, I know I shouldn't be in here but I just showed up and I don't remember how I got here." The words tumbled out quickly, nervous and apologetic.
