Yes ! all our biggest parties were always on a thursday, I even had a professor that hated lecturing on friday morning because it smelt like beer in the room! (jeudi CI is actually the motto of one of the student circles)
I'm watching her video rn and I find her view on parties very skewed (unless it's a culture thing, again). I'm introverted myself, and at first I didn't really like parties (because in my first living accommodations, the others were drunk every single night. Litterally. One like to brag that he drank such and such, when he had an appointment with his liver doctor at nine in the morning). But then I met a lot of my current friends, and most of our parties consisted of talking/joking/drinking (a lot but that's not the point, I've also had a lot if fun with them on nights I didn't wanna drink). I feel like the only version of a party that she knows of is going clubbing, which isn't really representative. But she's set her mind on it and doesn't want to change it.
Also, it's normal for her to want her 'me time' but socializing is an important part of uni, and spending all of your time alone isn't good for your ental healt (as I later learned, lol). Forcing myself to go to parties I thought I wouldn't enjoy, and actually enjoying myself, really helped a lot when I struggled, and I feel like she doesn't even want to try.
sorry if this is kind of rambly, but I recognize a lot of my younger self in what she says on parties/socializing, the only difference is I changed my mind pretty quickly, but she seems sets in her ways.
