Haha, humans are so silly, they will find danger where there is none, and where there is they walk straight into it...and they always have an excuse for why bad things happen, it's never about the stupid choices they made.
There are some things that seem to defy logic and explanation, but they are there for a reason beyond normal human understanding, and intuition is the way to deal with these.

13 is one of my lucky numbers and as for it falling on a Friday...it's just another day.

Superstition is a fantastic method of control. It's how religions have become so powerful.
