This world is very complete or perfect.
Starting from the rising of the sun to the setting of the sun, nature still shows its amazement or the beauty that welcomes its coming night for us to recall the time of the day is too much and much of the night or time for us to rest.
Sometimes man forgets at his own time working late into the night, who does not know the hours of rest just to pursue the mundane, but nature divides his time, that when his sun goes down and the time of the moon rises orange eyes rise again day.
