Describe a "Duchenne smile."
What will be an ideal response?
If the person is smiling, it is likely to be a "Duchenne smile," a genuine smile that is characterized by the skin crinkling around the corners of the eyes (i.e., forming crow's feet). Unlike polite smiles, Duchenne smiles are hard to fake because they involve involuntary muscles of the face.
