If Rudy Giuliani can't even manage civil discourse with his children and ex-spouse, how will he manage the various adversarial encounters he will face as President?

Rudy and Judy went to Harvard-bound Caroline's high school graduation today. They sat 30 yards from former Mrs. Giuliani Donna Hanover and son Andrew and never spoke to them.

When the commencement speaker, Sen. Charles Schumer, noted Giuliani's presence and the audience broke into applause, Hanover and her son, Andrew Giuliani, sat stone-faced and didn't clap.

But Hanover and Andrew jumped up and cheered when the Harvard-bound 17-year-old Caroline received her diploma from the tony Trinity School, while Giuliani and his wife, Judith, didn't even crack a smile.

Then Rudy and Judy ducked out early.

Rudy and Judith Giuliani avoided his children and ex-wife by arriving minutes before the ceremony began, entering through a side entrance, and they ducked out 10 minutes before it ended....At the graduation yesterday, Andrew did not acknowledge his father and stepmother and would not say whether the couple would join them later.

Rudy didn't attend Andrew's high-school graduation. Did he attend this one only so the press would report he was there?
