Well, in that case, let's not keep the next appointment waiting. Good luck and good skill sorting through everything and determining what's up with the mysterious memories from a mathless planet, sounds like you'll need it. You'll probably get a message from the DNA lab at some point.

Earth isn't mathless! We have very good mathematicians, the average person is just bad at math. We proved that there are no solutions for a^n + b^n = c^n where a, b, and c are positive integers and n is an integer greater than 2. She can't recite the proof to you but it's supposedly a rather difficult proof requiring modern techniques so it's probably a good demonstration of Earth's mathematical abilities. Uhhh, we proved the four color theorem, you know, the one where you only need four colors to color in a map on a euclidean plane such that no two sections of the map with a connected edge have the same color. That one required computers to prove, actually. We found the optimal solution to the moving sofa problem actually Celene does not know that because she died before it was proved. Tragic. No luck on the collatz conjecture though, maybe you've solved that one.

Regardless. Are they heading back to Summer's apartment now, or what?

Oh, that's Summer's favorite lemma from the proof that the cube root of two is irrational!

Yeah sure they can go back to her apartment if that's what Celene wants to do?

Sure, unless there's something Summer wants to do more.

...It's not because she's bad at having preferences!!! She swears!!! Celene is new to Eifwen and Nucleus and as such does not know a whole lot of locations!!!

Summer is nonetheless getting suspicious that Celene is bad at having preferences.

Annnnyways.

Apartment? Summer will have to lead the way, she has not memorized the route.

Sure, if Celene's gonna insist on being boooring, Summer can lead the way home.

She's not insisting on being boring! She's ok with coming along with anywhere Summer wants to bring her! She just doesn't know of any places herself!

...Does Celene wanna go shopping? Are there any basic possessions a Celene needs that she doesn't have?

Hmm. She doesn't actually know how to spend money yet. On Earth she would have a card she carried around to pay for things? And also she could integrate it into her phone and then tap her phone on a scanner to pay. Cash would work too, but she doesn't have cash. And... she does not in fact even know how to access her bank account yet. She could borrow money from Summer until she figures that out?

Probably a mobile phone would be useful. She needs her exobrain. But like, is that a thing here? How much would it cost?

...the thing is her default behavior for buying longterm expensive possessions is to shop around online looking for the best options on the cost/performance/durability frontier and pick one matching her desires and she can't exactly do that in person except she also doesn't know how to do it online because Eifweni internet and culture is different from Earth.

How does Summer generally go about that kind of thing?

...Okay fair enough online shopping isn't what Summer usually does but it's reasonable, they can just head back to the apartment. Celene can probably figure out how to do it, it's pretty easy, but Summer can help if Celene does need anything.

Yes of course Celene can borrow some of her money for now :p

Well uh, she has learned the hard way from living on Earth that getting used to having meaningful interactions with the economy without getting scammed or being overly paranoid is going to have a steep learning curve no matter what, and, well, she'll have to see how much spare money she has. Obviously more money means she can afford to take more risks and learn faster. Of course, Summer's assistance in teaching her how to do these things is appreciated <3.

I mean, jeez, you can definitely channel paranoia into penny-pinching if you really wanna but it's not, like, necessary, unless you find it fun?

In general she just finds it unpleasant to, say, buy something and then realize it was overpriced or to have it not have the features she wants or have it fall apart quickly and then be a waste of money. Probably this gets less bad if you have a lot of spare income to throw around but she never did, and wasting excess money trades off against important stuff.

Technically it trades off against important stuff even if you're rich, but it tends to feel, uh, less personal. At least to her.

...Did Earth fail to invent customer review statistics?

No, we have those, but they don't typically appear in physical stores? Come to think of it, she's not really sure why that is.

More pertinently, though, she doesn't really trust consumer reviews to have the information she needs? A single number isn't going to capture the specific minutia she's looking for, and they... don't typically take price into account? Nowadays there are more detailed summaries, saying "Consumers enjoyed feature X, but have noticed Y", and she obviously does take the information into account (she often likes looking at reddit for her reviews, which is a third party forum platform where she can sometimes get more informative comments), but it still requires a bit of work on her part to find and analyze multiple products, and see which one has the price/features she's looking for. She often likes looking at product recommendation lists online, which tend to be helpful. 

Oh gosh it's probably going to be difficult on Eifwen because the features on things will be more unfamiliar to her.

...if a single number isn't sufficient data, then surely you would prefer to use a client that lists more than one number??? Do you not have the little tradeoff curve graph thingies where you can choose two or three axes and see where products fall along them?

...No. No we do not. And anyways the actual information is in the text of the reviews, not in the numbers? For the most part everyone will just pick the maximum score on a product unless there's something terribly wrong with it.

...well, at least where she's from. In other cultures it's different.

Isn't that what a boolean is for???

Some people want more granulated opinion expression! And some people do use it for more granulated opinion expression, it's just that most people automatically click 5/5.

...So even if you are boiling it down to one number instead of collecting more detailed statistics, and it's not clear why you would, set up the UI so that "yeah sure this was good I guess" is a very quick and easy thing to input, and then there's a slightly more difficult thing you can do to indicate "I feel particularly strongly good about this" or "I've put thought into this and believe it's especially good?"

That's what the option to write a text review is for! Some sites even collate keywords and phrases found in the reviews!

...But writing a text review is way harder and makes much less legible data than filling out a survey, doesn't it?

Honestly she thinks she'd prefer writing the text review personally, but it is less legible to do statistics on, yes.

Wait, really? Even if you can just leave blank anything that takes more than a couple seconds of effort to fill in?
