Fuss loves maps and every time we tramp through the Elfin Forest he has to stop at the little kiosk and fish out a brochure, which he consults periodically during our journey.
Today he was particularly engrossed, staring at it long and hard while slowly walking up the path.
After a few minutes of intense inspection, he let it fall to his side and declared
"Dada? I'm getting some very strange readings."
I have no idea where this stuff comes from.
