Lucius Quintus Cincinnatus Lamar, Grand Trunk Railway Company of Canada v…
“ There is no fixed standard in the law by which a court is enabled to arbitrarily say in every case what conduct shall be considered reasonable and prudent, and what shall constitute ordinary care, under any and all circumstances. The terms 'ordinary care,' 'reasonable prudence,' and such like terms, as applied to the conduct and affairs of men, have a relative significance, and cannot be arbitrarily defined. What may be deemed ordinary care in one case may, under different surroundings and circumstances, be gross negligence. ”
