Violet
Harry and Ginny stood dumbfounded in the doorway of their home.
"... What?"
They both jumped when George stumbled up out of the foot deep carpet of pink balloons along their hallway.
"You're here early ... Surprise!"
The couple waded through the balloons, fighting off the pink faeries that kept trying to adorn them with posies until they reached him.
"George, what ..."
He rolled his eyes.
"This is your baby shower. Mum's convinced that seeing as she had all boys first, you're going to be the opposite."
Ginny's eyes widened as Harry stifled a grin.
"I think we went a bit overboard, but you know what she's like, and Perce still isn't quite used to moderation with our Wheezes products. Take a look upstairs first, so when Mum comes back you can pretend to be happily surprised rather than morbidly shocked." George said, an innocent look on his face so they didn't know whether he was pulling their leg. They approached the nursery with trepidation, until they once again found themselves in a doorway, dumbfounded.
"It's very ..."
"Pink," Ginny finished weakly.
"Well, it could be violet." Harry tried to appease, though he sounded far from convinced.
They took in everything before Ginny wrapped her arms around her husband and laughed.
"You can tell her it's a boy."
