>>936211919The gist of it is some student, usually a prefect or an older kid, uses whatever social or structural power that they have to make younger or less important kids do their bidding. It's kind of like bullies in anime getting others to buy them stuff or some shit but real. There are some accounts of sexual abuse from a few decades ago but for the most part it's trading convenience for favours.
I knew two guys who went to a public school and they both gave pretty similar descriptions. State schools have prefects as well but it's usually more of a tradition thing or telling students that they can put it on their CV if they carry books around for teachers and occasionally grass on other kids.
For your curiosity, since it can be different. Point is that the guy that Thunberg "found love" in is rich and, more unique to public schools, posh.
