The reappearing cloud...

What an odd day.. I was cycling along minding my own business, wearing a polo shirt because it was hot and sunny, then appeared this beast! From nowhere! I got absolutely soaked in a about 2 minutes of rain pellets... Then it disappeared again, the sun came back and it was hot again so I dried.. About 10 minutes later the cloud appeared again, once again I got soaked for a couple of minutes and then it disappeared, the sun came out and I dried... Crazy stuff!!! Beware, it takes no prisoners, just when you think you are safe it will appear, so run!! Fast!!....
