The angle between your signs — the same sign
Same element, same rhythm, same ruler: you speak the same language with no translation needed. The strength of this bond is how obvious it feels; its trap is the mirror: what annoys you in the other is often what you would rather not see in yourself.
Your elements — Earth and Earth
Two builders. You keep your word, you know what time is worth. The risk: routine taking the place of desire.
Your rhythms — mutable and mutable
Two mutable signs: you both adapt. Anything is possible, nothing is set — sometimes someone has to decide.
Your rulers
You share the same ruler, Mercury: words and wit, lived twice.
