Pig/Sagittarius and Dog/Capricorn meet at 65-70%, a cross pairing of the party and the chaperone. The Pig arrives laughing, wallet open; the Dog stands near the exit in something sensible, wondering when everyone will go home.
Improbably, this can warm up. Dog/Capricorn is a prude by its own admission, corseted and taciturn, and Pig/Sagittarius is exactly the good-humored force that can uncross those legs and make it live a little. The Dog's steadfast, quiet devotion gives the flighty-spending Pig something it rarely finds: gravity.
Pig/Sagittarius jokes loudly; Dog/Capricorn intimidates rooms into silence without trying. The Pig's humor bounces off the Dog's staid manner until, one evening, it lands, and the Dog's dry wit turns out to be excellent. Candy and flowers help.
Fun versus propriety, spending versus thrift. Dog/Capricorn disapproves of the Pig's fripperies and late nights; Pig/Sagittarius feels judged and performs harder. The Dog withdraws into taciturn silence, which the sociable Pig experiences as exile.
Pig/Sagittarius drags Dog/Capricorn out of the coffin it was climbing into fully dressed, and teaches it that pleasure is not a moral failing. Dog/Capricorn teaches the Pig that discipline is a kind of loyalty.
At 65-70%, Pig/Sagittarius and Dog/Capricorn are workable with effort: the corset and the confetti. Each has precisely what the other lacks, if neither resents the delivery.
