Daily photo - not such an interesting thing, but the night are of particular interest. The fact is that where there is light at night - there are people who comprise it, and the electricity that powers it. In other words - there is life out there watching TV in the evenings mother read stories to children, young men in love in a taxi driven by lovers of girls, and maybe even there the night of Hollywood restaurants. And where there is no light at night - there is no life. Or there - but there is no electricity. Either there is a war and used the blackout. In general, even if life is there - it's not a life.
