As anyone who comes from a small, southern town knows, it is extremely easy to pick up common sayings from those around you. Someone who’s pretty full of it is “all hat, no cattle.” Your perpetually late friend is “slower than molasses in January.” Someone who has just sold a business is “living in high cotton.”
