The reason is very simple! Troels' class' teacher in biology had forgotten that it should teach the class in biology for a lesson Wednesday 22/10.
And then Troels asked it if they should have her in the next lesson, and then the teacher suddenly remembered that it should have them the next lesson!
TGDML is condemning this behaviour and all TGDML members have agreed to suspend Troels from TGDML until he has taken his punishment: Having six giraffe beers from our "booz filler" (see the picture here very soon) in the period of a half hour!
