The phrase is catchy, but does it have any relevance? Sure it does, in a world of hate-- we need to take a page out of ancient scripture. Applying this proverb to human-relations-- makes perfect sense. In the social-arena, people are very hostile towards each other-- creating doubt "a gallon of vinegar". "A spoonful of honey", would be the total opposite; being truthful with your neighbor, instead of creating confrontation-- "will catch more flies" 💕
