"Life"

Life can be a fickled thing. One day, it passes you like a gentle breeze, so carefree and harmless you barely pay attention to it. Other days, it's a tornado. It strikes with no warning, and have you twisted in all directions, trying to tear you apart. Some times, it's a hurricane. You see the signs of a massive tempest heading your way, and you do the best to prepare for the worst. Despite all your preparations, when the calm ends, everything is torn apart, leaving you exposed to the harsh conditions.
When the storm passes, you have to find the will to pick yourself, and move forward. You can rebuild the damages, and replace anything that didn't survive. If it were meant to last, it would have weathered the storm with you. If it was blown away during the storm, best to forget about it because it would have crumbled when you needed it the most. Besides, there's a point in life where the direction you're heading will lead to constant downpours, and a sudden squall can blow you back on the right path.
