"Sirius, you're gonna spill paint everywhere!" Bellatrix yelled.

"I don't care."

"You should, this will be your house for a long time," Narcissa said, not looking up from her prim brush stroaks on her art parchment.

"Says who?  I'm not gonna LIVE HERE forever," Sirius scoffed, banging the paint down on the table.  It splashed over the sides a bit.

"Yes you will, this place is your birth right," Bella lectured.

"What's a birth right?" Regulus asked, wiping the paint with his hand and examining the color.

"It's like an inheritance for eldest children--something that will always belong to them because they were born first," Andromeda informed.

"Like me," Regulus said, looking up at his brother, who was painting his own hand.

"No, you get what's deeded to you," Cissy said.

"I'm Sirius's birth right," Regulus said.  "I belong to him since he was born first."  He made an experimental fist, and yellow oozed through the ends.

"Only THINGS belong to people," Narcissa snapped.

"Nuh-uh!" Sirius was suddenly very insistent.  "Kreacher belongs to Mother.  And Mother belongs to Father.  And Reggie belongs to ME."

"He won't always belong to you," Narcissa reasoned.  "What about when you get married?  You won't even live together then." 

Regulus looked at his brother with huge eyes.  "Yes we will," he said uncertainly.  "He can--he can marry me."

Cissy roared with laughter, and Bellatrix yelled, "You're so STUPID, you can't marry a BOY!"

"YES I CAN, SHUT UP!" Sirius screamed definatly, and hit her, leaving a smear of blue.  Reggie took his cue and wiped his hand on Cissy's dress.  Andromeda made them clean up and sent them to their rooms.
