Barrier
Humans have been building barriers for a long time.
Even when completely unnecessary, people will still create barriers to separate.
Whether to evaluate different objects, to aid in understanding, to make new discoveries through comparison, or to create comfortable distances, barriers have many advantages.
However, by discriminating based on differences, complicating things, comparing things to the point of dispute or even conflict, barriers can have disadvantages, too.
People insist on the proper enforcement of their own barriers, only for others to meet them in opposition. But, barriers are not straight lines established forever. Whether for good or bad, like a curtain blowing in the wind, they will yield in the direction they are pushed. Every day, these gentle fluctuations are always changing.
To speak with righteousness or evil,
forgiveness or condemnation,
happiness or sadness,
these barriers will merely flutter for all eternity.
