Why is it considered uncouth to eat some things with a spoon?

Why is it considered uncouth, perhaps even "saucy" to eat some things with a spoon? Dishes such as salsa, soup, and stew, which cannot be gripped with a fork, can only be handled with a spoon. Otherwise, to prefer to eat with a spoon rather than with a fork betrays a proclivity for incivility. When was the last time you, personally, used a spoon to eat your peas? If you're like most, probably as a young child being taught your manners. According to the Oxford Languages Dictionary, the definition of Civility is formal politeness and courtesy in behavior or speech. Civility entails forgoing convenience for politeness. This is evident in everyday discourse when one puts on a tie or ties back their hair, along with other choices which convey a preference for placing the esteem of others above one's own personal comfort. By demonstrating your good manners by eating your slippery peas with a fork instead of with a spoon, you present yourself as civil and refined, worthy of greater respect.
