Same world, different mentality

In a barbershop, a group of men were discussing how the world had changed and what the reasons for these changes could be. The barber, who had been cutting hair there for about forty-five years, told one of the young men in the discussion to look at a picture that had been on the wall for forty years; it was an image of the moon and stars. Then, the barber requested the young man go outside and look into the night sky, and come tell him what he saw up there. The young man did what was asked of him, and reported back that everything in the sky looked just like the picture. The barber replied, “Same world, different mentality.”
