Charlie had stayed at school over Christmas, which he generally offered to do at least one year in three since he was used to being away from his family over holidays. Plus the staff were a kind of family in the same way his colleagues at the Reserve had become family. Still, just like during the rest of the year there was only so much time you could spend with the same group of people without needing a break.
Thankfully everyone got some assigned time for quick visits to friends, family, or in Charlie's case the pub. He wouldn't have enough time to see family so the pub was preferable. He'd flown down to Hogsmeade, his prosthetic being a little less reliable and safe in the snow, but it still got him some exercise.
He hopped down carefully outside the Hog's Head, having eschewed the Three Broomsticks for the quieter atmosphere. He pushed open the door, slightly adapted broom still in hand. "Large Firewhiskey please, Aberforth," he said, looking for a decent perch.
