Monday
Monday has demonstrated extraordinary resilience across millennia. Various calendar reforms, revolutionary movements, and productivity gurus have attempted to abolish or restructure the work week. All have failed. Monday persists with the quiet tenacity of a concept that has achieved structural integration into human civilisation itself.
One cannot damage Monday, cannot wear it down through repeated assault. Each Monday arrives in pristine condition, unburdened by the failures of its predecessors. The temporal nature grants it perfect self-repair capabilities—by Tuesday, Monday has already begun regenerating for its next appearance.
Tank
Modern main battle tanks represent formidable feats of engineering durability. Composite armour, reactive protection systems, and reinforced structures allow tanks to withstand considerable punishment. A well-maintained tank may serve for decades, a testament to robust construction.
However, tanks remain fundamentally destructible. Anti-tank weapons, mines, mechanical failure, and simple neglect can render a tank inoperative. Museums display destroyed tanks as historical artefacts—Monday permits no such memorialisation. No trophy case contains a vanquished Monday, for none has ever been defeated.
