A smile is a facial expression formed by flexing the muscles near both ends of the mouth and by flexing muscles throughout the mouth. Some smiles include contraction of the muscles at the corner of the eyes (see 'Duchenne Smiling' below). Among humans, it is an expression denoting pleasure, sociability, 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 communication throughout the world. But there are large differences between different cultures. A smile can also be spontaneous or artificial.

Famous quotes containing the word smile:

    they smile in secret, looking over wasted lands,
    Blight and famine, plague and earthquake, roaring deeps and fiery sands,
    Clanging fights, and flaming towns, and sinking ships, and praying hands.
    Alfred Tennyson (1809–1892)

    Mr. [John] Barrymore’s smile was the smile of an actor who hates actors, and who knows that he is going to kill two or three before the play is over. I am not an actor-killer, but I like my Hamlets to dislike actors, if you know what I mean, and I think you don’t.
    Robert Benchley (1889–1945)

    A fair lady’s smile is worth more than a thousand ounces of gold.
    Chinese proverb.
