A/N: Song Two – Hot N Cold by Katy Perry

"I HATE JOHNNY MACMILLAN!" Lucy Weasley shouted, slamming the door to the bedroom that she and her older sister Molly shared. She sat on her bed and buried her face in a pillow. Molly came to sit beside her.

"You do know that, as an older sister, I'm required to make life hell for any boyfriend who mistreats you," Molly said. "What is it this time?" She was used to hearing her sister's rants about her boyfriend of five months. Well, sort of five months. They'd started dating five months ago, but for most of the time in between, they'd been having various rows.

"He's not my boyfriend anymore," Lucy muttered into her pillow.

Molly almost laughed, but didn't, because she knew her sister would kick her out. "Do you realize how many times you've said that, Lucy?"

"This time I mean it," Lucy said angrily. "I'm DONE with him changing his mind about everything."

"What was it this time?" Molly asked sympathetically.

"It wasn't exactly a this time," Lucy explained, her face still smothered with the pillow. "It's just…everything. I can't take it anymore. He changes his mind like normal people change their underwear." At this, neither of the girls could help but giggle.

"So…have you told him that you're dumping him yet?" Molly asked.

Lucy smiled into the pillow. "Trust me. I've made it very clear how I feel." Molly had no doubt about that. If Lucy wanted someone to know what she thought of them, she didn't waste words. She got right to the often-not-so-kind point.

Lucy stood up. "I'm going downstairs to owl Roxanne." With that, she left, still carrying the pillow.

A week later, Johnny and Lucy were dating again. When Molly heard the news, she just sighed. Someday, Lucy would realize that she hadn't been making the right decisions about him, that she was better off without him. Someday.
