On July 15, Andy and Gloria went on their first date, to the National Portrait Gallery, where they lingered to admire the newly unveiled portraits of Barack and Michelle Obama, then went down the block to grab a gelato. Neither wanted the date to end, so they wandered over to Hawk ’n’ Dove to get a frosé — millennial-speak for a frozen rosé. They answered each other’s first-date questions: She told him she was from Raleigh, the only daughter of an immigrant entrepreneur and a mother who prices computer parts; he told her he was an identical twin from Hartford, Conn., the son of a sociology professor and a nonprofit leader. They both love the water and prefer intimate gatherings with close friends over hitting the town. They both worked for their home state representatives and were eager to make a difference. To Gloria, Andy did not seem at all like a stereotypical Hill workaholic social climber.
