"Scalia enjoyed a warm relationship with fellow Justice Ruth Bader Ginsburg, considered a member of the court's liberal wing, with the two attending the opera together and even appearing together onstage as supernumeraries in Washington National Opera's 1994 production of Ariadne auf Naxos.[110] Ginsburg was a colleague of Scalia's on the D.C. Circuit, and the Scalias and the Ginsburgs had dinner together every New Year's Eve.[155]"
