Life goes on. (Rule of two walls (petals)).

24.04.2025 Russia pounded Kyiv with missiles and drones overnight, killing at least 12 people in the biggest attack on the Ukrainian capital this year

Rule of two walls: in case of a threat of fire, according to the two-wall rule, it is safer to be behind two walls in relation to an open space. If an explosive munition hits a building wall, the first, outer wall often collapses, creating debris and allowing the blast wave to enter the room, while the second wall saves people from it.
