Bit off topic but running with Caedes here:
The Chamber of the British House of Commons is a rectangular room with the Speaker's Chair at one end. Along one side, to the Speaker's right are the Government Benches and opposite them on the Speaker's left are the opposition benches.
In front of each set of benches a red line is drawn on the floor, and members are not permitted to cross the red line on their side.
The red lines are two sword lengths apart, preventing physical, personal attacks from one side on the other.
Now that is the correct way to set up a House!
