I’m at Dublin airport, waiting for my sister to come through arrivals. The airport is quiet tonight, a few families, a couple of guys with bunches of flowers, people hanging around on their phones or with paper cups of coffee.

A group of Spanish teenagers comes through the sliding doors, welcomed by an exuberant Dublin woman who bundles them together for a photo before ushering them towards the exit.

Groups of holiday makers arrive home from warmer climes, tanned and dressed inappropriately for the wet August night that awaits them outside the terminal.

Over the course of about twenty minutes, three middle aged women come through, Eastern European and Asian, greeted with hugs and kisses by their children and their tiny Irish grandchildren.

I could spend all evening here, watching these arrivals and reunions.

Dublin Airport is special to me. The scene of so many of my own departures and arrivals over the years. My first ever solo trip abroad (only my second trip ever in a plane), aged 16, when I went to central France for a few weeks to au pair and improve my French. How scared I was, and how scared my parents were, but I wanted to go and they didn’t hold me back.

Three years later, I was away again, this time to the Netherlands with my friend Louise; my aunt Catherine’s tent strapped to my huge rucksack. Mammy drove us to the airport that morning. We had no jobs, no clue what were doing, but we were youthfully optimistic that we’d find work for the summer. And we did.

I remember a big gang of family and friends coming to see me off when I departed for Japan, aged 22. My biggest trip yet. A year away, and so far away. I remember how we all tried to keep a brave face on things as we sat in one of the airport restaurants, waiting for the moment when I would have to say goodbye and take that lonely walk through to security. And I remember Daddy telling me that it would be ok if I didn’t like it and wanted to come home. We had no way of knowing how much I’d love it and that I’d end up staying for three years. And after that, there would be the multiple departures to the Canadian Arctic; all those journeys starting in Dublin Airport.

I remember the arrivals too. The time I came home from Japan with a shaved head and blue fingernails, and Mammy didn’t know what to think. The first time I travelled alone with Lily in her sling. And all those times I came home at short notice, for Jerry’s, Jimmy’s, Lillie’s, Nana’s funerals, cousins or uncles or my brother-in-law picking me up and often driving me directly to a wake late at night.

I remember the much more frequent arrivals during Daddy’s final seven or eight months, when I flew home from Aberdeen every few weeks. I no longer expected anyone to meet me at the airport. I’d take the bus home or I’d hop on a bus into the city and meet Daddy and Mammy at the hospital.

Tonight, I sit and look at the people waiting and arriving and departing and I wonder where they have come from, why they have flown into Dublin on this particular evening, and what awaits them when they pass through the doors and head for their destinations, each with their own fears and hopes, loves and losses, their own adventures and stories, pasts and futures.
