Smiles are facial expressions formed by flexing the muscles near both ends of the mouth. The smile can also be found around the eyes. Among humans, it is an expression denoting pleasure, joy, happiness, or amusement, but can also be an involuntary expression of anxiety, in which case it is known as a grimace. Smiling is something that is understood by everyone despite culture, race, or religion; it is internationally known. Cross-cultural studies have shown that smiling is a means of communicating emotions throughout the world, though there are large differences between different cultures. A smile can also be spontaneous or artificial.

With winds that sailors rail at.

As if he mock'd himself, and scorn'd his spirit

What guests were in her eyes; which parted thence,
As pearls from diamonds dropp'd.

When life flows along like a song;

And it always comes with the years,

Is the smile that comes through tears.
