Geometry of Expression...

I really wonder what would happen to our consciousness if we were scooped up from this planet and placed in another where human beings just like us exist, but the facial expressions for emotions were totally reversed. So whenever you would see an angry expression the person was actually joyful and whenever somebody would smile they would be angry. Imagine what just this alone would do to our consciousness. Seeing that one change in the geometry of expression. How would we change? How would our expressions change and how would we then interact with others. Suddenly a smile would not be pleasant but a frown would be.
