The scenery outside my Minsk-Gomel train window is changing.
The window is a big screen, behind it are people, nature, scenes, like from a movie.
Do we think about how we perceive what is outside the window - people, animals - as really living or as an element (episode) of cinema.
So we drove by, saw something or someone for a moment. So what's next? They've stayed at point A, we're moving. And every person we see is a lot of A points in relation to us. So we train passengers are a lot of B points that will never cross again.
