The teacher literally picked up a desk behind you???
The kid who caught the book was stalking.
Who was the kid stalking? Why were you playing "catch" with a textbook?
The teacher asked for my textbook and said “watch this” then let it fly.
Something about this story is hard to figure out, but then I never took German in school.
Took = sat down in
Stalking = talking. Typo
Let it fly = threw the book across the room
