Famous quotes containing the word practice:
“When any practice has become the fixed rule of the society in which we live, it is always wise to adhere to that rule, unless it call upon us to do something that is actually wrong. One should not offend the prejudices of the world, even if one is quite sure that they are prejudices.”
—Anthony Trollope (1815–1882)
“My paternal grandmother would not light a fire on the Sabbath and piled all Sunday’s washing-up in a bucket, to be dealt with on Monday morning, because the Sabbath was a day of rest—a practice that made my paternal grandfather, the village atheist, as mad as fire. Nevertheless, he willed five quid to the minister, just to be on the safe side.”
—Angela Carter (1940–1992)
