When you improvise on the spot, people are very reluctant to have soft moments or quiet moments or sad moments because they're trying to fill up the spaces. So they always go towards, "How come you're late?! You're supposed to have my shirt ready! You call this a dry cleaner?!" That's what happens. That's why improvising on the spot gets very dicey.
As societies grow decadent, the language grows decadent, too. Words are used to disguise, not to illuminate, action: you liberate a city by destroying it. Words are to confuse, so that at election time people will solemnly vote against their own interests.
