I worked at a place abroad and someone had etched one of these into the steel doors. As the two doors closed you came to see it. The locals reckoned it was a Brit that did it.
The residents must sleep soundly for no one to hear a lawn mower trundling around in the middle of the night. Silly thing to do but once the tables and chairs are out no one will be able to see it.
When my late sister was at Reading University she was engaged to a Agricultural student. There was a particularly obnoxious student who future BIL and his chums nicknamed 'Gums'
One night they marked out 'Gums' with lawn fertiliser outside his room
on the lawn of the Halls of residence. It showed up quite clearly and the villains of the peace were sent down for their sins.
then you sit on top of the head of the 'table' nearest the Crescent. In fact, I have an old business friend who has an apartment there - must catch up with him - and, no, he isn't called Richard.
