It wasn't what she was expecting, although "it" wasn't clear in her mind. After having received a briefing about how to interact with those who would soon join them, she and her friends huddled together in a room of this antiquated institution and waited. Their conversations were somewhat muted, quite a contrast to the voices chattering unintelligibly in the hallway. Soon a group of "boys and girls" entered, but from their appearance some appeared to be as old as the visitors' parents, maybe older.
Someone turned on the record player and cheerful Christmas carols filled the room and helped to relax some of the tension she had felt. She as about to discover "it" was the true spirit of the Christmas season, the giving of time and self in bringing joy to someone else.
The story took place at this historic building many years before its demise.
