Moon square Mars (orb 1.8°) creates concrete friction between the two planets. The orb is very tight; this describes a stable character pattern more than a passing reaction.
Here, Moon in Virgo in House 12 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 12 (retreat, contemplation, long time, and possible confinement), with Virgo style (precision, method, usefulness, and attention to detail); Mars in Gemini in House 9 brings action, courage, competition, and effort into House 9 (vision, belief, study, and wider horizons), with Gemini style (curiosity, language, movement, and mental adaptation).
Concrete friction: this aspect creates live tension between the inner child, mother image, and Mars: vulnerability, protection, or the need for safety can turn into anger, inhibition, or defense, sometimes through a weak, inhibiting, or castrating mother image. House 12 (retreat, contemplation, long time, and possible confinement) is in friction with House 9 (vision, belief, study, and wider horizons); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
