"Her Majesty has decided to introduce an interesting tradition," Xenomia thought. "It shows her warm attitude towards us; a personal greeting is very pleasant! Of course, Miss Grace's instructions on this matter... seem too complicated; it's unlikely that's what was intended. But I'll try to fulfill them, since it's necessary."
When Xenomia is called, or when several people pass by so that she isn't the first, the girl goes and gratefully receives and fulfills what is asked of her.
At the same time, she observes how these people manage to fulfill the instructions.
