I'm personally a realist.....I am not blind to the goings on around the world, as well as on our own soil. Nor to the happenings in the universe. Things are happening. Its hard for people in big cities to see it, since they are consumed with their own world. They must get to work, battling traffic, crowds, etc. They know that when they go to the store, their favorite foods are there. They expect it. They don't know where the food comes from, or how it got there....nor do they care. Its hot today, raining horribly tomorrow, then hot again. Was it like this last year? They don't know nor care. But.....
......take that all away. Take away the electricity, the blackberry phone, the laptop, the elevator, the ability to flush the toilet. Suddenly their world is turned upside down and they have no idea as to why. They have no idea how to grow a flower, much less a tomato plant. They don't know how to preserve, or conserve......wasteful of food and resources, they are now fish out of water. They get angry, hungry after one day, thirsty......they panic. Now you have blind rage and panic running everywhere, doing what they can or think they know in order to survive. Eventually they will spill out to our necks of the woods.
In that scenario, you can't just steer clear of that part of town, because its the WHOLE town/city. They are chasing YOU, looting your home, stealing everything you have, and possibly beating you to death in the process.
