Once, a wise man that visited a country village had forseen that all water sources from that place, at a certain day would go bad. Those who would drink of it would become mad.
None of the villagers paid any attention to that advice, except for one of the inhabitants of the village who began to build a private reservatoire for collecting water.
Soon that one villager had collected enough water to live for very long, when the day told by the advisor should come true.
Then, at that day all the inhabitans of the village became mad by drinking of the village’s water source except for that one inhabitant who had a private and safe self-collected water source.
Time passed.
Till one day, not bearing anymore to live in sanity amongst that all-surrounding madness the one still sound inhabitant decided to surrender to drink of the village’s water source.
People from the village remember that day as the day in which a madman came back to sanity.
