Happiness.... 😊😊Come from the internity of the heart 💟💟

A smile is a facial expression formed primarily by flexing the muscles at the sides of the mouth. Some smiles include a contraction of the muscles at the corner of the eyes, Smiles performed without the eye contraction may be perceived as insincere.

Among humans, smiling is an expression denoting pleasure, sociability, happiness, joy or amusement. It is distinct from a similar but usually involuntary expression of anxiety known as a grimace.
