Snake/Capricorn and Pig/Sagittarius meet at 51-56%, a cross pairing with the animals set directly opposite in the Chinese cycle. The lord of the manor mixes martinis while the lucky, laughing Pig invites the whole village in unannounced.
Both love luxury, which is the initial spark: Snake/Capricorn's expensive aristocratic taste meets Pig/Sagittarius's plush nest and open-handed charm, and for a while the two build something gorgeous. But the Snake wants a gigantic church wedding and standards; the Pig wants a good time and forgiveness on the bill.
Snake/Capricorn speaks in formality and raised eyebrows; Pig/Sagittarius in jokes and sobering truths delivered too loudly. The Snake finds the Pig vulgar in company; the Pig finds the Snake's traditional frost exhausting. Neither translation improves with volume.
Standards versus appetite. Snake/Capricorn frowns on modern laxity in dress and conduct, and the Pig is laxity in a party hat. The deeper opposition of Snake and Pig means the instincts grate even when the words are polite.
Pig/Sagittarius can teach Snake/Capricorn the compromise with the modern world it needs to keep sanity and bank account intact. Snake/Capricorn can teach the Pig that elegance is discipline. Both must stop keeping score first.
At 51-56%, Snake/Capricorn and Pig/Sagittarius are mismatched but possible: shared taste for the finer things, opposed instincts about everything else. Formal on paper, strained at breakfast.
