Life’s full of fools.
Some verses for reflection:

Pro 26:4-5 Do not answer a fool according to his folly, Or you will also be like him. Answer a fool according to his folly, lest he be wise in his own conceit.

Pro 13:20 He that walketh with wise [men] shall be wise: but a companion of fools shall be destroyed.

Pro 14:15 The simple believeth every word: but the prudent [man] looketh well to his going. A wise [man] feareth, and departeth from evil: but the fool rageth, and is confident. [He that is] soon angry dealeth foolishly: and a man of wicked devices is hated.

Pro 18:13 He that answereth a matter before he heareth [it], it [is] folly and shame unto him.

Pro 18:2 A fool hath no delight in understanding, but that his heart may discover itself

Ecc 10:12 The words of a wise man’s mouth [are] gracious; but the lips of a fool will swallow up himself.

Pro 29:11 A fool uttereth all his mind: but a wise [man] keepeth it in till afterwards.

Pro 15:7 The lips of the wise disperse knowledge: but the heart of the foolish [doeth] not so.
