International Pillow Fight Day in Warsaw - Poland

Obviously, I haven't posted any recently not just because I wanted to build the anticipation but I was in the hiatus for a while, just for awhile. April 2, was a special day for the Polish people in Warsaw the capital city and to some countries participating this Pillow Fight Day.
Since it's already spring and the weather is perfect for any outdoor events. The weather is warm, sunny and a bit cool, so no winter coats are needed. So,the plaza in Warsaw was filled with participants and expectators,I had no idea till a message posted in Couch Surfing forum inviting everyone to participate or simply watch the event. I took my camera with me to take some shots proving that I was there.
I met familiar faces from Warsaw Couch Surfing chapter, we had a little chit chat and taking pictures. The festival as they may say it lasted for 1 hour only, of course, who would like to be hit by a pillow for long hours. According to the event website:

One of our goals is to make these unique happenings in public space become a significant part of popular culture, partially replacing passive, non-social consumption experiences like watching television, and consciously celebrating public spaces in our cities as our “urban living rooms.” The result, we hope, will be a global community of participants in a world where people are constantly organizing and attending these happenings in every major city in the world.
