"Each man … finds life to be a discipline. Each has his separate form of discipline; but it bears upon the kindred spirit that is in every one of us, and strikes upon motives, sympathies, faculties, that run through the common humanity. Surely, you will not calculate any essential difference from mere appearances; for the light laughter that bubbles on the lip often mantles over brackish depths of sadness, and the serious look may be the sober veil that covers a divine peace. You know that the bosom can ache beneath diamond brooches, and how many blithe hearts dance under coarse wool."
