Everything you see in your reality started with a vibration that you atracted and translated in a thought. That thought you keep on thinking turns in to a belief. Your beliefs forms your belief-system. When a belief is powerful enough, you will expect that to happen. The more you belief in something the more prove you get in your reality so more of those things will turn in to real manifestation. So it does not matter what you see it all started in you as a thought. That why there is no wrong or right in what you are observing in your reality. Change your belief you change your reality.
