Logic* got a Needs Improvement on her quant test! Logic is never going to be able to learn math. She's a worthless person and it would be better for everyone around her if she were never born. Given the absence of a time machine, she's going to run off into the woods and live on hunting and fishing and mushrooming, where it doesn't MATTER if she's good at math, and if she eats a poisonous mushroom it would be FINE and NO ONE WOULD CARE, because her being alive would make everyone miserable.

Unfortunately, when she entered her closet to prepare for this, her closet turned into an interdimensional restaurant. Running away to an interdimensional restaurant seems even better than running away to the woods, so now she's clutching her favorite stuffed animal Teddy and drinking a cup of tea, which she isn't allowed to have because it has caffeine in it and she's too small for drugs. 

*This is not actually etymologically related to "logos" in the Teaching's language. 

Oh hey, there's someone else(A) here! Maybe A knows what's up. Hopefully Jana(B) can solve this mystery in time to catch B's train; the next one isn't for three hours.

"Hey, do you know why this is a restaurant and not the train station bathroom?"

"It's a restaurant that connects different universes! And time stops while you're in here. The logos gives us many blessings," she adds devoutly, wanting to make a good impression on the alien.

Jana waves an arm around and observes it move through space. "Time doesn't look stopped. What's the logos?"

"The logos created the universe and maintains it in every moment and tells us what we should be doing! --Time is only stopped outside. It goes fine in here. You can check if you want."

Jana runs to the door and checks. Sure enough, none of the people walking around the station make any progress while the door is shut.

"Wow! Now I definitely won't stay in here too long and miss my train. And you're from another universe? That needs maintaining all the time? Ours just keeps going with deterministic physics and nobody needs to do anything about it."

"Oh! The logos is the deterministic physics. You have it too!"

"Well, I sure thought we did but this whole restaurant that's in multiple universes thing is a big surprise! We should do experiments on it and publish and get famous and stuff. What's your universe like? Do you have a sun and a moon and fastplanet and hotplanet and redplanet and hugeplanet and ringplanet and sidewaysplanet and blueplanet?"

"I don't think we have it by those names," Logic says uncertainly. "We have Mercury and Venus and Mars and Jupiter and Saturn and Uranus and Neptune. Those are all named after mythological gods that aren't real."

"Cool! Hey, if you're from another universe with different names for things, how come you speak Convergentlanguage?

"I don't! I speak Romish."

"Hmmm. Do you want to try telling me some facts about Romish grammar so I can tell if it's almost the same as Convergentlanguage or if I'm just hearing Convergentlanguage when you're speaking something else?"

"Uh-- adjectives have to agree with their nouns, 'to' takes the genitive, the words you emphasize go at the end or the beginning of the sentence--"

"That's completely different--Iiiiii'm wildly hallucinating, aren't I. Uh, uh, can you say you're going to take some action and then wait a few seconds and then take it so I can see if what I hear you saying lets me make correct predictions?"

"I'm going to jump up and down." She waits one recitation of Joy To The Universe and then she does so.

"Okay, if I'm losing my mind I'm doing it consistently. I guess I'll accept my sense data and investigate the situation it looks like I'm in and not do anything especially risky. Which might mean I miss my train but I shouldn't run away to Bridgecity while I'm hallucinating anyway."

"Oh, are you running away? I'm running away too!"

"I am, yeah! My parents think I should go to more school and become an engineer or an architect or something mathy, but I don't actually like math even though I'm good at it and I'm metaphorically sick of them and I want to go get a job and not live with them anymore for a few years."

And when Jana(A) comes back A will have been living independently with NO trigonometry and A's parents(B) will have to admit B were wrong about what would make A happy even if it turns out A just needed a break, because B weren't planning to give A one. Except now A's maybe hallucinating and should go home or to the hospital, or has just discovered other universes with language magic and should go to a physicist or a newspaper or someone in government. A'll figure out which sooner or later.

"Oh, I'm terrible at math! I was running off to go live in the woods because I'm worthless and everyone's lives would be better off without me because I got Needs Improvement on my quant test."

"Getting bad grades is the worst but probably your family will still miss you. Which doesn't mean you shouldn't run away! You should do whatever you want. Just, probably it won't make anyone else's life better, just yours. Are you going to go live with the autarkoids or are you trying to pull a This Is My Mountain*?"

* The most famous instance of a genre of escapist/coming-of-age novels in which someone(A), most often a teenager, ends up lost in the wilderness for some reason, survives by hunting and gathering, overcomes various trials, eventually makes contact with civilization again, and either joins an autarkyvillage or just tells A's family A's alive and then goes right back to the wilderness. 

"I don't know what an autarkoid is so probably the second thing? I'm going to go hunt and fish and eat mushrooms." She leaves out the part of the plan where she was going to eat a poisonous mushroom and die because then the alien might stop her. "I'm Logic."

"I'm Jana. I wouldn't want to pull a This is My Mountain because I like having toilets and I'm too scared of dying but if you pull it off it'll be totally awesome."

"Dying isn't bad," Logic announces. "Everyone would be better off if I were dead."

"If you die in the woods you won't get preserved in time! And what good would you being dead do anybody?"

"Well, they wouldn't have to put up with me," Logic says. She thinks this is a great point.
