In October 2023 I visited Amsterdam. Every day during my staying there I saw activists who brought to the main square footwear, heart-shaped balloons and pieces of paper with information about kidnapped by Hamas. I saw people, who at the moment geographically are far from horrible event, but they are close connected in feelings to those, who have encountered the greatest tragedy in their lives. They are strangers to each other and probably they even never met each other in person. In spite of that one people feel other people pain. They pray for safety and life's. Those days I became an accidental witness, but later I found out about project KidnappedFromIsrael, which was widespread across six continents. This campaign became one of the most widespread guerilla public artworks in history.
