December twenty-fifth was Christmas Day, but it was also the day of the Yule Ball. For the first time in Harry’s memory, Hogwarts remained full of students, with the only ones returning home being the first years, second years and the third years who weren’t asked to the Ball. So because of that, Gryffindor Tower that morning was not its usual quiet building, but rather for the first half of the morning it was packed with everyone as they received their presents and wished their friends and acquaintances a merry Christmas. Then at around lunchtime, all the girls disappeared up to their dorms to get ready for the Yule Ball. When that happened Harry and Ron simply shrugged and went outside to play in the snow alongside Fred, George, Lee Jordan and all the other fourth year Gryffindor boys, starting up a massive snowball fight that spread out throughout half the school grounds.
