I don't even know why she would be learning Latin other than to appear smart and for the Dark academia aesthetic. Admittedly, I do a bit of Latin here and there but I study early modern history and I have a use for it. I don't know if she likes learning, I think she only likes it to fill in the gaps of her day to justify staying at home, as it looks a bit more socially acceptable to stay at home if you are studying. Plus the studying gives her reasons not to go out and it's an excuse for her to stay shut up in her room all day
For Ruby it's purely for the aesthetic and the fact that she can hold it over peoples heads.
"O0oH I StUDy laTIn f0r ThE SaKe 0f LeARnInG" Yeah ok Rubert sit down.
She did the same thing with her morning bible readings a few months ago. A couple videos back (morning routine #763) she started The Book of Genesis because she wanted to read through the entire bible because she wanted to further understand biblical literary references and pointed out how culturally important it was/is (both of which are very Eurocentric ways of viewing it Roobee but I digress). Ruby wouldn't be caught dead studying subject matters that weren't worthy/advanced/prestigious enough and most importantly must fit into the dark macadamia aesthetic.
A bit OT but Ruby is apparently reading Babel (I know some have touched on this in the threads and I wanted to add to it). Her reading Babel is absolutely hilarious because she is going to view it as this amazing dark academia book which I guess it is in a way but it goes so much deeper than that. There is so much in Babel to unpack and it just skims the surface of the dangers of dark academia, elitism, colonialism, etc. But unfortunately all of that would go right over Rubys head and she would see it as nothing more than her dream life of studying at Oxford. Ruby is the (less intelligent) epitome of the character Letty and people like Letty who exist in todays world. Ugh if anyone has read Babel I would love chat because there's just so much to say but I'll leave it there for now.
