Horse/Libra and Dog/Aries meet at 80-85%, a cross pairing with old-fashioned gravity. The most physically beautiful DoubleSign in the book meets the stern believer in twinned souls, and each is exactly what the other was shopping for.
Dog/Aries has held out for a soul separated from its own at creation, and Horse/Libra, an ambulatory Versailles, certainly looks the part; the deeper draw is that the Dog sees the limitless mind behind the reflection. Horse/Libra, tired of being admired as a facade, finds the Dog's austere sincerity irresistible.
Dog/Aries speaks in eternal verities, plain and firm; Horse/Libra answers with polish and the occasional catty flourish. It works because the Dog never flatters, so its praise is the only review the Horse fully believes.
Friction lives where Dog/Aries's austerity meets Horse/Libra's frippery: the Dog rides hard against vanity and shopping-window glances, and the Horse bristles at being reformed. The Dog must also resist matchmaking and managing the Horse's life.
Horse/Libra puts substance behind the beauty faster with a partner who values nothing else, and Dog/Aries learns that a little ornament is not moral decay. The Horse gains depth, the Dog gains delight.
At 80-85%, Horse/Libra and Dog/Aries show strong compatibility. Beauty finally believed, loyalty finally rewarded; it lasts if the sermons stay short and the mirrors stay few.
