While being in Croatia, I have seen a strange custom of humans. It seems some humans don't like clean houses. So I thought that this must be kind of greeting, or kind of wallpapering of homes (probably for homeless people, as OUTSIDE is their home). I was told that this kind of "greeting" or "wallpapering" is called "Graffiti".
just kidding... I can not draw in any way. But it felt interesting to adorn myself with borrowed plumes
