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 Taurus in House 2 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 2 (resources, values, and security), with Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance); Mars in Aquarius in House 12 brings action, courage, competition, and effort into House 12 (retreat, contemplation, long time, and possible confinement), with Aquarius style (independence, networks, distance, and collective change).
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 2 (resources, values, and security) is in friction with House 12 (retreat, contemplation, long time, and possible confinement); this can create blockage, inhibition, overreaction, or repeated conflict between the two fields.
