Snake/Sagittarius and Rooster/Capricorn meet at 80-85%, a cross pairing with old family sympathy between Snake and Rooster. A mind that reads everyone like a see-through comic book meets the one person written in invisible ink.
Canon says Snake/Sagittarius thrives on surprise and needs a partner it cannot make out with clarity; unflappable Rooster/Capricorn, all grace under pressure, is exactly that delicious puzzle. Rooster/Capricorn, in turn, values a partner perceptive enough to respect the work ethic everyone else once mocked.
Snake/Sagittarius looks before it leaps and reads between every line; Rooster/Capricorn says little and means all of it. The result is an efficient, oddly restful conversation where neither wastes words and both notice everything.
Friction comes from pace. Rooster/Capricorn never stops climbing, and Snake/Sagittarius likes to rest on its laurels between insights. To the climber that looks like coasting; to the observer, the climbing never seems to pause for the view.
Rooster/Capricorn keeps Snake/Sagittarius from resting while the race moves on; Snake/Sagittarius teaches the unflappable one that people are texts worth reading, not just heaps to climb. Perception and persistence make a formidable trade.
At 80-85%, Snake/Sagittarius and Rooster/Capricorn are strongly compatible, the reader and the unreadable, an alliance of perception and iron work ethic with only tempo to argue about.
