Moon square Lilith (orb 1.1°) 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 Leo in House 3 brings personal dream, play, inner child, childhood imprint, mother figure, mother image, optimism, and inner rhythm into House 3 (speech, learning, and the close environment), with Leo style (presence, pride, creation, and the wish to be seen); Lilith in Taurus in House 12 brings pure ideal, absolute demand, fascination, and refusal of compromise into House 12 (retreat, contemplation, long time, and possible confinement), with Taurus style (nature, good food, physical sensuality, roots, resources, and perseverance).
Concrete friction: this aspect creates tension between attachment, childhood imprint, mother image, personal dream, and a non-negotiable ideal. House 3 (speech, learning, and the close environment) 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.
