One fool makes many.
One foot is better than two crutches.
One good head is better than a hundred strong hands.
One good mother is worth a hundred schoolmasters.
One good turn deserves another.
One half of the world does not know how the other half lives.
One has lived too near a wood to be frightened by owls.
One honest word is better than two oaths.
One hour's sleep before midnight is worth three after.
One hour today is worth two tomorrow.
One love drives out another.
One man makes a chair and another man sits in it.
One man may steal a horse while another may not look over a hedge.
One man's meat is another man's poison.
One may sooner fall than rise.
One may think that dares not speak.
One misfortune comes on the neck of another.
One must draw the line somewhere.
One must drink as one brews.
One must howl with the wolves.
One never loses anything by politeness.
One never loses by doing a good turn.
