Bad things do happen for a reason. Here is the reason.
For bad things not to happen only good things would always be happening.
Then, "good" would lose relative distinction with less "good". The less good would start to look bad in comparison.
Suddenly, what use to seem only good would be bad by contrast.
Is this crazy talk?
No way!
The poor in America have bathrooms with flush toilets, microwave ovens, TV, satellite service, refrigerators, ovens, automatic legal rights, free medical treatment and social nets to fall back on. These are America's downtrodden!
Contrast this "awful state" with the majority of the world where there are no toilets, no clean drinking water, no technology or medical treatment.
What is a "good" day like in a backward town in Africa where AIDS is spreading and children are wandering the streets with no parents and bloated bellies?
You see, what is "good" is pretty much relative. So is what is "bad".
Bad things happen to us because we expect better things...much better things....and don't get them.
