Air thinks, water feels: a meeting of head and heart. In astrology the pair forms a quincunx (five signs apart). Signs five apart have little in common, so the relationship needs adjustment and curiosity.

## At a glance

Traditional harmony rating: ★★☆☆☆ (based on the aspect between the signs). Real relationships depend on whole birth charts and, above all, on the people.
