If a series of events can go wrong, it will do so in the worst possible sequence. After things have gone from bad to worse, the cycle will repeat itself. When the going gets tough, everyone leaves. If you wait it will go away. If it was bad, it'll come back.
Nothing is always.
Everything is something. No matter what goes wrong, there is always someone who knew it would. Complex problems have simple, easy to understand wrong answers. To err is human, but to really foul things up, requires a computer. A computer program does what you tell it to do, not what you want it to do.
