That's sort of a weird concept that they're trying to mime at her, but, okay? She wasn't even going to ask that question.
She refills her pitcher of water, bringing it back over to the food acquisition area to set down on a nearby table. This done, she turns to consider the table of food and plates. Well, it might be kind of tricky to return to her guest room with as much food as she wants to eat and her pitcher of water. It'd be much easier to just eat right here, at these tables. But then someone might try to talk to her, which would be terrible. She already failed step one earlier, with Lissa. Best to take her prizes and leave, then, before anyone else can get the impression that it's okay to ask her questions right now.
Vetareh gets a plate, piles it on with quite a lot of food that needs to be carefully balanced for fear of a food avalanche, then retrieves her pitcher of water and saunters off with her prize. Bye everyone, she's going to go back to not being social. ... She could go not be social in a garden, though. Hmm. It's a bit damp, but her clothing's still keeping her warm and dry enough, and the scenery is pretty enough. Yep, eating out by herself in a pretty garden, that seems to be the way to go.
She finds herself a pretty and out of the way section of garden to have herself a picnic, sitting on the grass in her very fancy clothes and looking utterly unconcerned with getting dirt or grass stains on it.
