Greta Thunberg started skipping school on Fridays in 2018 to sit outside Sweden’s parliament and demand action on climate change. The protest spread around the world. Years later, when she was told activists were still carrying on the weekly demonstrations, she laughed.

“They still do that?” she asked.

Well, yes, Greta. They kept Fridays open.

It’s a funny little time capsule from an era when adults spoke of Thunberg’s every utterance as if it had been handed down on a stone tablet. She was compared to Joan of Arc, nominated for the Nobel Peace Prize and celebrated for sailing across the Atlantic in 2019 rather than taking a commercial flight. At the United Nations, she delivered the “How dare you?” speech that became her signature. The return logistics, which involved crew members flying, got considerably less attention than the crossing.

Thunberg was a teenager when all that began. The grown-ups who turned a school strike into a test of everyone else’s moral seriousness were old enough to know better. They could have argued for their preferred energy policies and defended the costs. Instead, too many acted as though disagreeing with the proposal meant you’d failed a character test.

These days, some of Thunberg’s biggest headlines have come from her activism over Gaza, including her participation in a flotilla that Israeli authorities intercepted in 2025. Meanwhile, the climate campaign she helped launch still has people showing up on Fridays. Whatever you think of their politics, you have to give them this: They stuck with the assignment.

A laugh doesn’t prove Thunberg has abandoned her climate views or that she was mocking the people who still protest. She may simply have been surprised. But there’s something wonderfully awkward about the founder of a weekly movement reacting to news that it still meets like someone who just discovered she’s still on the bowling league’s email list.

The Friday crowd can take it as a compliment. They built a movement that can carry on without its founder. Apparently, it can even carry on without her knowing.
