As we pulled out of the driveway last night, I asked Marinda if we were crazy for loading our four sleeping kids into the minivan at 11:30 pm to drive to the airport and greet people who we knew very little about: their last name, that they’d had a long day of flights from the other side of the world, and maybe they had some kids. By the time we returned at nearly 2:00 am, the answer was clear – we hadn’t been crazy.
