It is that feeling that appears when one nears the end of a journey not having found what was sought. I sat on a near-empty bus, leaning my head against the window, peering outside for whatever I could gain from Hong Kong. It didn't look like much. I had escaped the grey city for vast, open, grey sky.
Just then, the woman in front of me took out her camera and started taking photos, as if trying to bring back whatever bits of Hong Kong she could from her very last morning in the city. I started observing her to see what she considered photo-worthy, and realised all the photos she took were of apartments. She must not have many of those where she comes from.
