As mathematics never was her favourite class, Doreen decided to make it a fast lunch. It would not make a good impression if she was late on her first day, so she rushed towards room 27. Period four obviously had not started yet, because the classroom was empty. Mister Stroem was not even there yet.
Suddenly, she got an idea. After dropping her bag on the table somewhere in the middle of the classroom, Doreen walked over to the black chalkboard. She searched for an appropriate crayon and with it she draw a green frog on the board. Well, maybe it looked more like a lizard to somebody else. Anyway, she got so creative with it, that she completely forgot that she was waiting for her class to start and started to hum.
