Old old sayings: "A stitch in time saves nine." (Repair now or it's more work later to fix it.) "Never buy a pig in a poke" (Poke = sack, so 'examine before buying'.) "Give him enough rope and he'll hang himself." (Let a liar continue to lie in detail, and eventually he'll contradict himself and be proven a liar.) "You can't really know a man until you've walked a mile in his shoes." "A winner never quits, and a quitter never wins." "A penny saved is a penny earned." "Red sky in morning, sailor take warning; red sky at night, sailor's delight." (Weather forecast mnemonic.) "If you want something done fast, ask a busy person to do it." -- Local to Chicago (known as 'the Windy City'): "Don't like the weather? Just wait 15 minutes..." "If you ever needed both the air conditioner and the furnace in the same day, then you must live in Chicago." "Everywhere else in the country, voting is a right and a duty -- in Chicago, it's a sport." "Hollywood is all hype, New York is all talk, but Chicago is all work."
