They lie and they lie and they lie. When they’re done lying, they rest, briefly, then—once they’ve caught their breath—they begin a second round of lying, believing (accurately) that these lies are more convincing than the originals.
Everyone within earshot is exposed. Some are lulled into believing every syllable while others, more jaded by prior experience, are able to resist the sirens and continue thinking for themselves. There are, however, far fewer of these than there are of the deeply zombified believers and, sadly, with each passing generation there are even fewer still.
