((slowly raises hand)) I'm definitely one of those people who acts like an imbecile in lectures and seminars, mostly because I'm super awkward and have social anxiety, so I'm prone to freezing and going silent I'm not especially intelligent but my grades are good (though I'm lazy af at the moment and need to try harder), and I usually know the material for seminars pretty well - I just feel like I'm being judged like hell when I speak up, and never got used to talking or asking for help in class anyway.I think it may be this. I knew so many people like this at uni; from how they speak up in class, or how they come across in conversation, you'd never think they're deep-thinking or particularly intelligent. But then when you saw their assignments & their exam grades, it was like a whole different person. I'm pretty sure they wanted to save their hard work & thoughts for themselves, lest anyone copy it or something, idk. or maybe she doesn't want to come across as too deep & mature which is in keeping with her desire to be seemingly as childlike as possible.
in general, i think we only see the tip of the iceberg with ruby. If she were as surface-level in her degree as she is in her videos, there's no way she'd be getting such good grades at uni. Similarly, if she were as child-like and rigid in real life as in her videos, she'd never foster friendships like she did & find friends to share a flat with.
I think Ruby could be quite similar; she seems hesitant in videos with her friends/other people, and tends to be socially awkward. It could be that she can't get the words out, or judges what she's planning to say so intensely that she ends up saying very little (like me lmaooo), or she could just, as someone else mentioned, be tailoring her reviews to her younger audience. I wish she'd make more in-depth videos about her favourite books and genres and really go hardcore with the referencing tbf. She could even link it in with the Uni study stuff by talking over research she did for a long essay?
