Nothing causes more panic than rain for a lot of people. I suspect more people have had panic attacks trying to escape rain than from something grave. It is a natural phenomenon that people have endured for ages. But still, most humans are simply not used to the idea and dislike it. There is a desperate urge to run for cover as if the rain would kill the person. The justification always is the discomfort of wearing wet clothing.
Big deal. Mind over Matter. Get wet! Enjoy the shower! Unite with nature! It really is not that big a deal and if for a moment you can forget the inconvenience of wet clothing, you actually enjoy the chillness and the overall sensation. Its just beautiful. Except when I am on my way to work. Even then, I live with the inconvenience.
