Mauerbauertraurigkeit

Humans are complicated

Their behavior is complex

It is unpredictable

Scientists have researched and analyzed the behavior

They attempt to categorize them to different groups

They find the factors that trigger a certain reaction

They study the social influence to understand their action

They ask many questions

And find various versions of the answer

However, there is always that small unpredictability factor

There is no algorithm that predicts the next action

We never know what triggers them

People suddenly lose hope in others

They withdraw in their shells to heal

To pace themselves and prepare for the war

Science cannot define or sort it

It just happens

It is Mauerbauertraurigkeit 

The inexplicable urge to push people away,

Even close friends who we really like
