There’s this old Polish (and general central-European/Slavic) tradition of “Ĺmigus dyngus” which is totally not possible to translate into English, but is also called “wet Monday”. Basically, people run around and pour water on each other. It used to be that young boys were getting young girls wet, but now everyone can get wet and also possibly sick since it’s still kinda cold.
With that explanation out of the way, enjoy some wet Amber goodness and happy Easter if you celebrate it or just have fun over the weekend.
