"Oh. Bread's like my favorite food. Sometimes I just have bread with nothing on it for a snack."

"Favorite foods are nice! I really love this one type of noodles but I can't have too many, so my favorite's the broth they come in."

"Do we have them here or is this from your planet?"

"From my planet!"

"You should tell everybody about it in a video and people'll probably try to make it for you with stuff we have."

"That'd be pretty weird! I could talk lots about different foods, though, I bet, even if I don't know all the ingredients..."

"There can be Earth food theme menus in restaurants and stuff."

She laughs. "Humans would get such weird expressions at that! It'd be like someone from China visiting Chinatown but better. - China's a country and Chinatown is a neighborhood in a different country with lots of people whose ancestors were from China."

"Why are there lots of people from China in a different country?"

"I think China had a thing for a while where they had lots of economic problems? So lots of people left to go be railroad workers in America, and now their grandkids are other types of workers since America doesn't need tons of railroad workers anymore."

"How come America didn't have enough people to be railroad workers though?"

"Railroads were new and also America had been expanding again - America's a country that happened when Britain invaded this really big continent that had less technology, and Britain made a colony there that rebelled a bit later and became America, but then America kept invading the rest of the continent so they ended up with a lot of land and not a lot of people, and all their big settlements were on the coasts with nothing in between them, so they needed a really huge railroad project so the cities could trade. American workers I think didn't want to work on the railroad because it didn't pay well and was dangerous, but the Chinese workers were more desperate."

"Oh, I guess that makes sense. So now America's got lots of extra purples."

"America doesn't have a caste system, actually, so the American people who would've been in purple jobs became other stuff. Lots of the Chinese people are still poor, though."

"Oh, huh. - that's weird."

"I think most humans don't do castes?"

"Most of them? But it's been invented somewhere?"

"I think in India and maybe Japan? Japan's pretty small and was isolationist until recently but India's a decent size..."

"I think castes had to be invented here too but it was a long time ago so now everybody does it."

"I think it's pretty unlikely to spread? India's still under British rule and the British didn't put the caste system anywhere else they're ruling."

"Maybe they didn't invent the right ones."

"Dunno. I think humans might just not be good at castes? It sounds like the type of thing humans would start a rebellion over, though humans start rebellions over a lot."

"They'd start a rebellion over... castes? Really?"

"They've started rebellions over unfair taxes and disproportionate votes and farmers not owning their own land and kings eating during a famine and the same family getting elected suspiciously often..."

"I think we have the votes thing because of castes."
