We sometimes laugh from ear to ear, but it would be impossible for a smile to be wider than the distance between our eyes.

The glance embroiders in joy, knits in pain, and sews in boredom.
When indifferent, the eye takes stills, when interested, movies.
Laughter is regional: a smile extends over the whole face.

Our expression and our words never coincide, which is why the animals don't understand us.

A women knows how to keep quiet when she is in the right, whereas a man, when he is in the right, will keep on talking.

The flower in the vase smiles, but no longer laughs.

Laughter, while it lasts, slackens and unbraces the mind, weakens the faculties and causes a kind of remissness and dissolution in all the powers of the soul; and thus it may be looked on as weakness in the composition of human nature. But if we consider the frequent relieves we receive from it and how often it breaks the gloom which is apt to depress the mind and damp our spirits, with transient, unexpected gleams of joy, one would take care not to grow too wise for so great a pleasure of life.
