“Life is a mirror: if you frown at it, it frowns back; if you smile, it returns the greeting.”

“To frown at pleasure, and to smile in pain.”

“Come, then, affliction, if my Father wills, and be my frowning friend. A friend that frowns is better than a smiling enemy.”

“Behind a frowning providence
He hides a smiling face.”

“When Fortune smiles, I smile to think
How quickly she will frown.”

“Have you noticed that the imbecile always smiles? Man's first frown is the first touch of God on his forehead. The touch of thought.”

“How do you do that?” Mennis asked, frowning.
“What?”
“Smile so much.”
“Oh, I’m just a happy person.”

“Her very frowns are fairer far
Than smiles of other maidens are.”

“But by that time you do not much care whether she smiles or frowns. Why could she not have smiled when her smiles would have filled you with ecstasy? Everything comes too late in this world.”

“Sneer, frown, and be miserable, for tomorrow you live.”
