What these two planets are doing

The emotional reflex, formed before language.At 90° the question this pairing raises is whether conversation flows or constantly needs translating, set against whether comfort is instinctive or has to be negotiated. A square puts those two demands at odds rather than in agreement, which is why this aspect is read as work rather than ease.
Mercury moves 14.6 times slower than moon, so the faster one sets how long the exact angle holds.
