I have a fond memory of transiting singapore ... or perhaps dubai. It was night, and the place was pretty much empty, asleep. Anyway I ended up having breakfast with an Australian woman. We were the only 2 in a large open restaurant. We had a very open and honest conversation about our lives - hopes, dreams, failures. Then we headed off in different directions.
Airports are a liminal space at the best of times, but 4am particularly so.
