Unlike United States, most of Europe celebrates Easter Monday. In some Eastern European countries - Poland, Czech Republic, Slovakia and Hungary - it is called Wet Monday. The name comes from the custom of boys dousing girls with buckets of water early in the day. The tradition dates back to pre-Christian times and alludes to a pagan fertility ritual.
I am happy to report that in modern times, girls retaliate with a vengeance and it has become a day long water battle carried out on the city streets. So be forewarned: if you ever find yourself in Eastern Europe on a Wet Monday, remember to carry your umbrella!
This photo is the closest I could come to spraying you…oops, I hope I did not get any water on your keyboard ;-)
