I've been thinking since then about arrivals and departures, how closely they are bound. In our case, this morning, inseparably. But they are always linked: coming and going, giving and taking, opening and closing.
It's not quite as simple as "what goes up must come down," but for every joyous embrace of welcome at the airport, there is the bittersweet hug at the end of the visit, dear ones flying back across the country. I'll be counting the days until they return and I can head to Arrivals again — this time, for real.
