"There's really not a lot to do," Romilda said. She set the basket on the table and opened it, waving her wand to charm the double sets of plates, glasses, silverware to make three (so it wasn't obvious that it had been intended for Gilbert to join them, of course!) and then grabbed the tablecloth. "Just grab plates, silverware, and containers! And help yourselves. The more the merrier for any meal, I always say."
Which was the absolute truth; she loved sharing food with as many people as possible. That there was a special treat in this lunch was just a bonus. She lifted the basket for a moment to spread the tablecloth, then set the basket on top of it, starting to unpack. If they helped, it would go faster, but it wasn't hard.
