I’ve never gotten detention and I don’t think it has been a thing in any school I’ve been to. Maybe they made us skip recess? But I don’t have a memory of having something called detention or “kvarsittning” in any school I’ve been to.
I cried about one then I didn’t have to do it because I got to explain the reason I hadn’t done my homework and my Mum wrote a note.
The other time I vomited because the stress of having that slip hanging over me because I was struggling to do the homework was too much for the El. The teacher never actually processed it though so all that stress for nothing.
