A couple of kids dobbed some poor fool in but they finished up getting 3 cuts each for telling porkies.
To this day they never found out who the culprits were. After the heat died down, and by way of apology to Cyril, we drew a picture of a window with curtains on a large piece of project paper and stuck it on the wall of the cubical. Below it we had a small table we grabbed from the caretakers room and a old vase. We put some dried long grass to represent native flora in the vase and placed the vase on top of a race form. Cyril thought it was rather touching.
