Sirius laughed, in a bark. "You're one to talk, Miss Bones. You think you know everything based on outward appearances and words and hearsay, don't you? Why does that make you think you're so much better than anyone else? How can you think you know more than, say, me, when in fact, you know such a small fraction about anything at all." He sat forward, resting his hands against the desk, his fingers along the map.
"Don't let James hear you say you weren't impressed," he said, his annoyance flaring up. He and James and Remus and Peter were DAMN proud of that map. A silly Hufflepuff child who thinks she knows everything? It wasn't that he was hurt to find that she claimed to not be impressed, but that he was annoyed about it.
