smooth Quotes

And Jacob said to Rebekah his mother, Behold,Esau my brother is a hairy man, and I am a smooth man.

—Bible (Old Testament)

We do not like the confiding, the intimate, the ingratiating, the hail-fellow-well-met, but prefer the unapproachable, the hard-bitten, the recalcitrant, the sinister, the malignant, the saturnine, the cross-grained and the cankered, and the howling wilderness to the amenities of civilization, the irascible to the affable, the prickly to the smooth.We have no damned fellow- feeling at all.

—Grieve
