Sand dust and propaganda

In the meanwhile, there is little to see of the red Saharan dust that turned everything orange in Andalusia in March, reducing visibility and irritating throats. Many people washed their walls and houses with steam cleaners or painted it new, but many others preferred not to waste such a precious good like water (or did not have the money to buy steam cleaners, or both); red dust can still be found on many buildings and parts or it which are difficult to access (roofs, higher parts of façades). 

I think propaganda behaves like Saharan dust. Even months or years after its spreading, elements of it are still to be found in our houses and brains and lives. People still react if they believe it, if it was true.

This is a part of the roof of Victoria Kent's train station in Malaga city (Spain). The sky is blue now, but red dust may stick there for many more months.
