In this chappie I'm trying to portray Julie as jealous of Harry and his fame even though she knows he hates it. Does it work?
Molly stood at the foot of the stairs. "PERCY, FRED, GEORGE, RON, HARRY, JULIE AND GINNY! UP! FIRST DAY OF SCHOOL!"
From the girl's room, someone was running and from Ron's and Harry's room, someone was running. The bathroom door slammed shut and three people banged into each other. From the voices, Ginny was the first into the bathroom.
Ten minutes later, the two girls were running downstairs, Julie banged into Arthur, who dropped his toast, a piece landing on Ginny's head. She handed it to him and they ran to Molly.
"Mama, do my hair please." Ginny said.
"Me first Mama!" Julie said.
Molly put the food on the big table and flicked her wand at their heads. Ginny's hair was pulled back into a braid and Julie had pigtails. They sat at the table, grabbing the good bits, Ginny standing on her chair to reach. Meanwhile, Arthur had restacked his toast and Fred and George came running downstairs, banging into him.
"Sorry Dad!" They said and ran for the table and dug in. A dignified Percy came downstairs, helping Arthur with the toast. He went to sit and Ron streaked downstairs, banging into Arthur. The toast fell once again.
"I give up." He muttered. Ron slid into a seat as Harry came downstairs, his clothes on backwards.
"Mama!" he said. Molly turned and rolled her eyes, flicking her wand and the clothes were fixed. "Fred and George, you have to clean your room today and you have to give me your Dad's wand." They handed it to her and she gave it to Arthur and continued.
"Percy, keep an eye out for your siblings." "And don't forget to have fun!" Arthur said going out the door. "Percy, you take Ron and Harry, then Fred and George will go, and then I'll come with the girls." Percy got into the fireplace and said "Wizarding School For Children From Wizarding Families." Fred and George jumped in after him, mimicking him, and then they were gone. Molly sighed, rolled her eyes and stepped in the fireplace. "Wizarding School For Children From Wizarding Families." she said and she was away.
When she stepped out of the fireplace at the school, Percy was brushing off the girls best he could but they were squirming. She flicked her wand in their direction and their dresses were nice and neat. A lady came over. "Hello again Mrs. Weasley. I'm glad this meeting isn't about Fred and George's behaviour." Molly smiled "I hope we don't need another such meeting. Today is three of my children's first day. Ginny, who is five" she pointed to Ginny who smiled at her, "And Harry and Julie, they joined the family last year, and they're Ronald's age, six." The Headmistress looked at them and raised an eyebrow when she saw Harry's scar. Julie rolled her eyes.
"Right. Come along then Harry, Julie and Ginny. The rest of you know the way." The twins ducked past Molly and ran to their class. Percy put up with her kisses and walked off. Molly knelt down to her four youngest. "You lot better be good." she said as she kissed them goodbye. As Molly flooed away, Ginny's lower lip started to tremble. Ron put an arm around her shoulder. "Don't worry Ginny, you'll see her at lunchtime." He kissed the top of her head and led Harry and Julie to the class, dropping Ginny off at her room. The teacher there caught sight of them and came over. "Hullo Ronald. Who are these two?" "Harry and Julie Potter-Weasley. They live at my house now." The teacher smiled "I see. Go sit down, Ron. Harry and Julie, follow me." She went to the front of the classroom and clapped her hands
"Attention class! We have two new pupils joining us today. Harry Potter and his sister, Julie." The six year olds started whispering and staring. The teacher motioned to two empty seats in the back behind Ron "Have a seat." They sat down and the class began. Recess came and the children went outside to play before they ate. Julie and Harry held hands, scared. Ron ran over to Ginny to say hullo. A crowd formed round the new kids.
"Is it true you defeated You-Know-Who?" A girl asked. Harry nodded. "Why isn't your bloody sister famous too? She a Squib?" someone said rudely.
Julie flushed, she hadn't shown her powers very well yet-Harry and Ron more so then her. Except for the twin thing. Harry punched the kid and the kid went down. "Leave my sister alone!" Harry yelled. Julie hit Harry, mad.
He was already well known. Let her speak up for herself. She and Harry started fighting and they were pulled apart and brought into the Headmistress' office so she could fire-call Molly.
