She is sitting in the library, studying. It's her most common pastime, by hours; spending time with her sister is more enjoyable but Jaromira prefers to socialize more broadly and Katarzyna would only get in the way. This is better on net; the two of them share a room, so it isn't as though her sister's time is entirely hogged by the other girls who call this boarding school "home." Or at least "prison." Katarzyna doesn't mind it, though; the school library is excellent, and basic manners and care for the books has endeared her to the librarian to a sufficient degree to lubricate the interlibrary loans process when there's something she wants to read that they don't have.
"I don't believe that it is. But the ones that there are are very different from the ones that we have, so they stand out."
"Oh--a few months ago there was a biology lab assignment and I wanted to do an interesting variation that didn't exactly match the lab handout, so I went to Jaromira and explained the issue and she told me exactly what to say when I was asking permission to do it differently. Two weeks ago we had a group project in history and one of the girls in my group was flat-out insufferable, so Jaromira would distract her any time she started talking, so that the rest of us could get the project done."
"Didn't know how to take no for an answer. She kept suggesting things and people kept explaining why they wouldn't work or would make things more difficult and she kept bringing up the same things over and over again no matter how many times we explained that they wouldn't work."
"I'm not great at it myself so I'm just imagining her saying 'look, a squirrel' fifty times."
Giggle. "Oh, it was definitely subtler than that--Ava, the girl's name was Ava, would say, 'oh, you know what I think we should do here?' and Jaromira would come up with a guess and engage Ava in trying to shoot down Jaromira's idea--and then Jaromira would let her succeed so Ava felt like she was being listened to, and the next time she tried to speak up Jaromira would notice beforehand and say something to her completely unrelated to the project--"
"Thanks! I'm pretty sure it's pedestrian and middle-class but have not previously had much wherewithal to refine my tastes!"
"The upperclass non-pedestrian restaurants I've been to were with my father and stepmother. It may have soured me on them somewhat."
"This is much better. When my mother was alive she used to take my sister and I to these suspicious-looking little hole-in-the-wall places with surprisingly delicious food."
