outbreak
Occurrence is the phenomenon of inconvenient events popping up the moment you least prepare. Troubles, glitches, and maladies appear as if mocking your lack of foresight, with no warning and no apology. They establish new realities with the momentum of a neighbor who barges in uninvited. Each time it occurs, people sigh 'not again' and scramble for a remedy. As long as patience and countermeasures exist, occurrence will never lose its purpose.
