"She laughs at everything you say. Why? Because she has fine teeth"

Benjamin Franklin's quote is a humorous way of recommending that someone is making fun of everything you say since they find you amusing. It implies that the person has a common sense of humor and is enjoying your business. The phrase "fine teeth" is a metaphor for a sharp wit and intelligence. Franklin is recommending that the individual is laughing since they value your wit and intelligence. It is a compliment to the individual, suggesting that they have the ability to recognize and value your intelligence and humor. The quote is a suggestion to be mindful of the business we keep and to appreciate those who can acknowledge and value our intelligence and wit. It is likewise a suggestion to be conscious of our own wit and intelligence and to use it to make others laugh.
