( CNN) Supreme Court Justice Ruth Bader Ginsburg extolled the #MeToo motion and revealed one of her own experiences with sexual harassment in deeply personal observations Sunday at the Sundance Film Festival.

“Every woman of my vintage knows what sexual harassment is, although we didn’t have a name for it, ” she told the session’s moderator, Nina Totenberg, before detailing an incident when she was a student at Cornell in the 1950 s and preparing for a chemistry test.

“My instructor said … ‘I’ll give you a practice exam, ‘” Ginsburg said. The next day she discovered that the practice quiz was, in fact, the real exam. “And I knew exactly what he wanted in return, ” she told. “And that’s just one of many examples.”
