Excitement for The End is the default, knerjerk reaction for those who have been told their whole lives that the end is coming soon.
The moment there is anything newsworthy or any organisation change, desperation to justify a lifetime of disappointment, the need for social acceptance and self-reinforcement of a flaky faith cause them to break out in these pitiable exclamations.
An earthquake, a war, a new president, global warming, a new bible, Bethels closing. They ache for validation of their beliefs and obsessively see The End in every innocuous event.
It's a sad, sad thing to behold because it will only ever lead to more disappointment and more desperation.
