George took a moment and tried to work out the best way to explain them. Immediately he stuck an arm out and chest height to where they sat on the bench. 
"They're about this big, live to work for whoever they live with." He decided to pick his words carefully, in case of offending Sadie. Muggleborns didn't exactly understand house elves werent slaves. He turned back however and waited for Seine's response.

The food as amazing and so was the castle. Despite how afraid he had been, he felt like everything had changed now and it felt good. Honestly the whole place felt fantastic and relaxing and outright brilliant. It was going to be good, he could feel it. No one seemed to mind him at all, maybe that was because Saide and Seine didn't know, but it's not like anyone else had said anything either. Hogwarts really was amazing, truly, completely. 

"No way. He's /your/ dad? Me and my Mum used to listen every week. I had no idea." George blurted. He felt a strange bubbling of sadness before being thankful the entire conversation shifted again. Surely if Sadie hasn't been a muggleborn, the whole thing would have been less interesting. He watched her confusion and laughed along, smirking at her. "You'll get used to it all." George turned back to his soup and made an effort to eat more than he was actually hungry for.

George followed Sadie's gaze and furrowed an eyebrow. It was a little hideous, but enough times seeing the sight and surely theyd all grow immune. 
"My parents used to say ghosts are people who were afraid to die." He added quietly. Around them the room came to life, Hogwarts Ghosts appearing from all sides of the room, soaring above the tables, some above tables, others circling the room. George followed a few around the room, watching quietlg from his seat.
