The exhibition One is the Loneliest Number ((AV 17) gallery, Vilnius, Lithuania, 2022) focused on loneliness and the fears associated with it. Humans have evolved into social beings that live in larger groups and rely on cooperation in order to survive. Since the late 19th century, the number of people living and feeling alone has been rising. This is mostly due to the aftereffects of capitalism and the industrial revolution, both of which led to urbanisation and changes in the traditional family. Loneliness has been described as a modern disease or even an epidemic. The exhibition focuses on the paradox of being alone in a crowd and sees loneliness not only as an emotional state but also as a threat of being forgotten.
