Famous quotes containing the word companion:
“My companion assumes to know my mood and habit of thought, and we go on from explanation to explanation, until all is said that words can, and we leave matters just as they were at first, because of that vicious assumption.”
—Ralph Waldo Emerson (1803–1882)
“Guilt is perhaps the most painful companion of death.”
—Elisabeth Kübler-Ross (b. 1926)
“He that outlives a wife whom he has long loved, sees himself disjoined from the only mind that has the same hopes, and fears, and interest; from the only companion with whom he has shared much good and evil; and with whom he could set his mind at liberty, to retrace the past or anticipate the future. The continuity of being is lacerated; the settled course of sentiment and action is stopped; and life stands suspended and motionless.”
—Samuel Johnson (1709–1784)
