Well, if you would have had a closer look at their paintings you would have realized a few things and that they are old, very old.
They were trying to tell you the story of their life by painting not one, but many pieces of art onto the wall.
These many artworks have been painted in many different art styles. This tells me they learned from many great old artists, so they must be very old by now.
They have left their mum, who you can see right below them with the rubiks cube, which she obviously couldn't solve, because they wanted to search for their father, of whom nobody knew who he was.
So, they traveled the world as you can see Russia, China, Arabia, Romania and also Greece. I can see they have also been to the Underworld or the Hades and Paris as well as in India, but I have no idea where they might have met the flying horse.
They have been searching for so many years on every place on Earth and under the ground for their father. Now, they have stranded in Belgium ... have they found their father? I don't know, and you?
BTW: Tell the residents that their house is now a valuable work of art and that they are all rich now ... virtually ;)
I would be quite !DERANGED if I didn't give you a !BEER and a !COFFEEA for this $trdo post 😉
