It shone on his desk on which there were sheets with homework which he hadn't done yet. On the floor right next to his desk lied even more sheets many of which weren't touched for months. Besides his desk was a cabinet were he stuffed all things in and which seemed to burst open at a moment's notice.
Then he looked at the shotgun lying on the floor with which he just had shot himself.
He closed his eyes.
