The Burden of Maintenance
The melancholic and agitated are born so. Their nurture may affect growth and development, but not foundation. In the same way, a nascent cherry tree can grow into nothing but a cherry tree.
While one can take measures to cultivate tools for proper maintenance, one cannot assume a different species. It is the responsibility of the agitated melancholic to seek the additional resources it requires for upkeep. Its dietary needs are greater than more self-sustaining counterparts.
While no nature is inherently rotten, the agitated melancholic is better equipped with the tools of destruction and mutilation. It is this unstable sapling that must be surveilled to preserve a personal and collective welfare.
