Arthur was lying on the couch. No one had suprisingly be there. So he was really enjoying it. He rarely got some time alone. He didn't think about manner as he lied down on his chest, his head resting on two hands looking down as he was reading some magazine.
He was dressed in rather casual clothes and was wearing two different socks by accident. But since he was alone, he didn't really care. With being too focused on reading he hadn't heard someone coming in.
