Be kindly affectioned one to another with brotherly love.–ROM. xii. 10.
In her tongue is the law of kindness.–PROV. xxxi. 26.

Since trifles make the sum of human things, And half our misery from our foibles springs; Since life’s best joys consist in peace and ease, And though but few can serve, yet all can please; Oh, let the ungentle spirit learn from hence, A small unkindness is a great offence.
HANNAH MORE.
All usefulness and all comfort may be prevented by an unkind, a sour, crabbed temper of mind,–a mind that can bear with no difference of opinion or temperament. A spirit of fault-finding; an unsatisfied temper; a constant irritability; little inequalities in the look, the temper, or the manner; a brow cloudy and dissatisfied–your husband or your wife cannot tell why–will more than neutralize all the good you can do, and render life anything but a blessing.
ALBERT BARNES.
You have not fulfilled every duty, unless you have fulfilled that of being pleasant.
