A group of elderly women turned a stretch of the Seine embankment into their own dance floor. Moving to music, they laughed and swayed with obvious energy. Their cheerful routine unfolds three kilometers from parts of Paris where fires are burning. On one side of the city, emergency crews deal with the flames; on the other, life carries on as if nothing is happening. The contrast between the two scenes is what makes the moment stand out. Images of the dancing grandmothers circulated widely precisely because of that juxtaposition. A single evening in Paris managed to hold both panic and playfulness at once.
