The time: Late one night in November 2011. The place: Blue Moose Taphouse, Iowa City, Iowa. The circumstances: Megan's friend Kim pulled a "How I Met Your Mother" and asked Billy--whom she'd known from working together at the University of Iowa-- if he'd met Megan before. He had not. They talked for awhile, Megan pulling all the stops trying to impress Billy with a riveting description of her honors thesis, Billy listening politely and trying to figure out how to ask Megan for her number. He did; they had coffee a few days later and the rest, as they say, is history. And then... : Exactly 6 years later, Billy stood at the bottom of the stairs to their house in Richmond, Virginia, and asked Megan if she wanted to hang out for a while longer, like maybe forever. She said yes.
