Communication & Mind

- De-escalation protocol: “Are we problem-solving or venting?” If venting, Aries listens; if solving, Cancer gives the green light.
- Avoid mind-reading: Cancer’s mood shifts aren’t obvious to Aries—state needs. Aries’ bluntness isn’t hostility—signal tone shifts.

Trust & Boundaries
- Transparency is the antidote to Neptune-style confusion. Share contexts for schedule changes and friendships.
- Mind the words: Mars square Mercury in synastry can feel like constant criticism. Slow the tempo; mirror back before responding.
