Finally, he stepped forward and knocked on Petra's door before he could chicken out. It seemed that the second the sound echoed through the hall he regretted his decision. His hand hovered in the air like he was going to knock again, but in reality he was frozen in shock at his own actions. In that long moment standing there in the hall he contemplated running away, disappearing down the hall and pretending like he never showed up there in the first place. But it was too late. He could hear the shuffling on the other side of the door. He felt like he was suffocating, struggling to breathe as he waited for the door to open.
