This is the second version of this story. Slightly longer, as you see. Please review!
Tonks, Sirius and the wand
"Oi! That's my wand!" Remus buried his face in his arms, leaning over the table, laughing so the tears flowed as Sirius chased Tonks around the kitchen, trying to get back his wand.
"Then come and get it!" She shrieked with laughter and held the wand high over her head, waving it teasingly, so sparks flew out of the tip.
"Give it back, Nymphadora!" Sirius almost caught her, when she stopped for a second, in shock over hearing him use her first name.
"Hey! Don't call me that!" Remus snorted with laughter, knowing that it was her automatic response to all mentions of her name.
"Stupid little niece, that's better?" Remus spat wine all over the table. He reminded himself never to drink with Tonks and Sirius together again.
"It's Tonks, for Merlin's sake!" Tonks brandished her uncle's wand and Sirius ducked for the shower of sparks.
"Nympha-" Remus sighed and wiped a few tears out of the corners of his eyes. They were just hopeless.
"No!" Sirius ducked a more deliberate hex, and they kept running around the kitchen.
"-dora, give my wand back!" Remus poured himself more wine. If they weren't going to enjoy this excellent elf-made drink, their loss.
"Only if you call me Tonks!" Sirius backed a few steps, hands raised in mock fright. Remus put a hand over his face.
"All right..." Remus knew Sirius all too well to believe this.
"Here you go." Tonks threw the wand back to its rightful owner, and Remus wondered what would come next.
"Thank you, Nymphadora." Ah yes, quite obvious. He pretended to become very interested in his wine, so they wouldn't see his face.
"Hey! I told you not to call me -" Tonks's hair turned black and fiery red.
"Little niece, little niece... you've got a lot to learn about the world. And hey, that's still my wand!" She had jumped at Sirius and snatched his wand back, and Sirius immediately started chasing her again.
"Only if you call me Tonks!" Remus just sighed and gulped down his wine as quick as he could.
"All right, all right, Nymphadora..." They really were hopeless.
