Born at this point in Virgo season
Born in the last stretch of Virgo, this person arrives as the season's careful work is nearly done and the mind is already looking ahead. They notice small errors in other people's plans before anyone else does. That same eye can make them the one who checks everything twice, then wonders why the day feels so long. Their gift is precision. Their lesson is letting a draft be good enough.
