I was wondering before why "Mona Lisa" is very famous. Mona Lisa is an oil painting by Leonardo da Vinci. The painting shows a woman looking out at the viewer with an enigmatic smile. Now, what's with that smile?
It was said that her smile is 83% happy, 9% disgusted, 6% fearful, 2% angry, less than 1% neutral, and 0% not surprised at all. For me, her smile seems to hide something inside. It's like her smile was fake. She might be really sad but she's just trying to hide the sorrow.
No matter what we think about her smile, we can't really tell the meaning of her smile. It is difficult to tell the emotions in just one glance. Her smile will still remain as a mystery.
