Every time I’m at the airport travelling, this photo of the windows almost always gets taken. Here is the most recent one as I returned home from my trip to Asia in 2017. 🙂
For some pontificating: This photo shows window panes among window panes and shows the window of opportunity to the world. Since it is a photo of an airport at the departure area, the world is literally at your feet as a passenger as you fly to a destination of your own choosing. The window is your world.
