Pig/Sagittarius and Horse/Taurus land at 50-50%, a true cross pairing with no shared animal or sign to lean on. One is a lucky, laughing spender forever hosting the party; the other is a modest homebody for whom home is the remembered womb.
The attraction is the pull of opposites: Pig/Sagittarius finds the Horse/Taurus steadiness restful, and Horse/Taurus finds the Pig's humor and swagger intoxicating, exactly the prodding lover it secretly needs. But the Pig wants to go out and pick up the check, and the Horse would stay inside all day if it could.
Pig/Sagittarius talks in punch lines and grand plans; Horse/Taurus downplays its own qualities and hates being rushed. The Pig mistakes modesty for dullness, the Horse mistakes exuberance for recklessness, and both are a little bit right.
Money and motion. Pig/Sagittarius lives beyond its means and calls it hospitality; security-minded Horse/Taurus feels every frivolous purchase as a hole in the safety net. When the Pig plans a trip, the Horse plans an excuse to stay home.
Horse/Taurus can learn from Pig/Sagittarius that the world outside the nest is warmer than feared, and worth showing off in. Pig/Sagittarius can learn that a safety net is not a cage. Both lessons take patience neither starts with.
At 50-50%, Pig/Sagittarius and Horse/Taurus are mismatched but possible. It works only if the Pig comes home more and the Horse goes out more, and both actually mean it.
