If it's a bright, sunny day in a park, you will tend to feel bright and sunny yourself. But if clouds are lowering darkly over a cemetery, you will probably squat down and get set for a good scare. If you are shown a mansion in Texas, you will begin to think about what it's like to be rich. If the setting is a city slum, you will begin to think about the problems of the poor.
