Cancer vs Gemini: the two signs side by side
Cancer is water and cardinal, ruled by the Moon. Gemini is air and mutable, ruled by Mercury. Different elements means they take the world in differently, which is where both the interest and the friction live. Different modalities means they move at different speeds — one starts, the other holds or adapts.
