Christina Zografou wasn’t among the thousands of Athenians who gathered in Syntagma square on Sunday to support Prime Minister Alexis Tsipras.

That’s not because the 21-year-old university student doesn’t support the efforts of his three-week-old government. Rather it’s because Zografou is more anxious than hopeful about what Tsipras will achieve. On Monday night, talks between Greece and its European creditors foundered after Tsipras’s government said the euro area’s proposal to extend existing bailout commitments was “absurd” and “unacceptable.”

“I’m not optimistic this government won’t end up like the others; they aren’t prepared,” Zografou said. “The rallies show how exhausted Greek society is, how it’s a society on the brink.”

While opinion polls in Greece point to unprecedented support for the new government, they also show an undercurrent of concern. A Kapa survey of 1,015 Greeks published the day of the rally showed that hope was the overwhelming feeling chosen to describe Tsipras’s handling of the crisis since his election. The most prevalent feeling after that was anxiety.

The rallies “place an even greater burden on the government to deliver a ’new deal’ for Greece,” said Spyros Economides, a professor at the London School of Economics. “If they don’t deliver, the goodwill generated among the electorate up to now could quickly be eroded.”
