The end of the world?
It really sounded like a plausible explanation.
People didn't think that way at first. They only found the rain strange and the phenomena rather incredible. It might not make sense, but they were only curious. Very few people were really bothered by it.
However, when the end of the world was mentioned, it attracted much attention and became all that everybody could think about.
The end of the world!
Raindrops that didn't wet clothes, and snow that didn't melt and would vaporize instantly. The end of the world seemed to be a perfect explanation for such a strange phenomenon. All the changes had been caused by the end of the world.
If the end of the world was approaching, nothing would seem strange anymore.
"That's why! The end of the world is coming! That's why so many strange things are happening!"
"I see! That's why my stomach has been upset the whole day! The end of the world is coming!"
