Born at this point in Cancer season
Born on June 30, early in Cancer, this person comes into the season while its themes are still taking shape. The Sun has only just entered the sign, so care for home and family feels new and somewhat untested. Feeling shaped by the Moon meets the warmth Venus brings, which makes the wish for steady closeness easy to name. The work is letting that closeness grow at its own pace, which is slower than the heart would like.
