Celebration
When Harry was at the legal wizarding age to drink, he did so with fervor. Drink after drink, he sat at the bar. He had Hermione and Ron beside him, both having been of legal age months before him.
They celebrated for many things that night: the defeat of Voldemort, the marriage of Ron and Hermione, Harry's own engagement to Ginny, and the happiness they felt thanks to their strong friendship.
By the end of the night, Harry was so drunk he could barely stand on his own two legs. He giggled and acted silly; he reacted to things Ron or Hermione said in a loud and brash way. Hermione sighed, rolled her eyes and told Ron to deliver him safely back home before she apparated to the Burrow.
"Come on, mate, let's see if Ginny will take you in for the night." Ron hefted Harry onto his shoulder with some trouble, before apparating to Ginny's small apartment. While Harry and she were still engaged, Harry thought it best for them not to live together. He still had things he needed to take care of at Grimmauld Place – places where the wood was eaten through by termites; dust an inch thick in some places where Kreacher refused to clean.
Ron knocked on the door, watching lights flicker on in the house almost automatically, and smiled at his sister as she opened the door. He flung Harry onto her, laughed out a "Now he's yours!" before apparating back to his home and to Hermione who was waiting for him in bed.
"So this is what you do when I tell you I'm pregnant. Good thing I didn't mention they were twins!" Ginny giggled with a warm smile stretching across her face.
