Or when dealing with each other, for that matter. In Lojban, it is grammatically incorrect for someone to give me vague directions like "we are at the pub to the left of the central plaza". They would instead have to say something like "we-not-you are now at the only pub to the left (when seen from the cinema) of the only plaza".
Imagine political debates where imprecise language and double meaning are much harder to express. Mmm...
