Ox/Pisces and Dragon/Aries meet at 65-70%, the patient strategist and the born gambler. One lets the game play out to its foregone conclusion; the other bets the bank before the cards are even dealt.
Dragon/Aries leads the pack on luck and talent, in the boardroom and in bed, and the calm, decorous Ox/Pisces finds the sheer confidence magnetic. The Ox, in turn, offers the beautifully over-decorated nest and mate-for-life mutual respect a Dragon secretly needs after conquering things all day.
Ox/Pisces says little and reads everything, its uncanny interpersonal radar predicting outcomes ahead of time; Dragon/Aries declares intentions loudly and calls it discussion. The Ox usually already knows how the argument ends, which the Dragon finds either soothing or infuriating.
Friction lives in tempo and ego. The Dragon's bet-the-bank boldness alarms a homebody who prizes calm and decorum, while the Aries passion for its own ego crowds a partner who wins by quiet. The Ox waits out storms; the Dragon hates being waited out.
Dragon/Aries learns from Ox/Pisces that not doing anything can be the winning move, and that caring for someone means crawling out from under one's own shadow. Ox/Pisces learns that some banks deserve to be bet, occasionally.
At 65-70%, Ox/Pisces and Dragon/Aries are workable with effort. The gambler and the chess player; profitable together once they agree which game is being played.
