You hate schooltrips, maybe because you hate your class. You don't have friends in it, you want your old class back.

Your teacher organized a class trip because your classmates wanted one. Everyone has to share rooms, however, noone wants to take you with them, and you don't neccesarily want to join them either.

"Listen, well find a solution. Worst case you will spend the night with me, got it?"

Your teacher spoke with you, in private. He's aware of the trouble he could cause himself.
