Y/n was sitting on a chair in her porch, waiting for Harry to come outside. 
His birthday was coming soon, and she knew the moment when he would find out about him being a wizard was coming soon. 
"Honey!" her mother called. "It's getting hot out, come inside and get a glass of lemonade!"

Y/n ran inside. Her mom's lemonade was always the best.

"Mum," she asked. Y/n put a straw into her lemonade and sipped it delightfully.

"What is it?"

"Can Harry stay over tonight?" Y/n looked hopefully at her mother.

"One," her mom said sternly. "He's a boy and I won't let him in the house for a sleepiver until you're of age. And two, it's not allowed."

"But why not, Mum? It's just one day."

"No. Dumbledore would destroy me. With those annoying calm ways."

And then there was a period of time around Harry's birthday that no one was home at Number 4, Privet Drive.

Y/n's mother told her not to worry. He would be back soon. 
But he was her best friend, of course she had to worry! 
These thoughts and nore spun in her head all the time until...

"Hello, is Y/n home?"

"HARRY!" Y/n ran from the house and hugged him.

Harry cleared his throat loudly. "You're squeezing my guts."

"Ooh, sorry, Harry." Y/n brushed herself off quickly. "Where have you been? We were worried sick!"

"YOU were worried sick," said Ms. Prewett, smiling at the boy. Harry laughed.

"So listen, Y/n... I'm going to this boarding school... and um... but I'll be back in the summer?" Harry said quickly and awkwardly.

Y/n smiled. "That's okay. Which boarding school is it?"

"It's... er... St. Brutus' Institute for Criminal Boys."

Y/n burst out laughing. "Best lie ever."

Harry pretended to look confused. "Uh- no- not a lie- it'd real-"

"Just say Hogwarts!" said Y/n, positively howling with laughter now.

Harry gaped. "How'd you know?"

"I'm going there too, silly!"

She knew Harry would be a little angry for not telling him before, but they worked it out and were happier than ever.
