Born at this point in Virgo season

Born in the final stretch of Virgo, this person carries the season's habit of checking things twice. Late in the sign, the urge to sort, refine, and fix sits close to the surface. A friend asks for help moving a couch, and they arrive with a plan, a tape measure, and a list of possible problems. Their care is real, but it can land as doubt for people who only wanted company. Learning to offer help without the inspection is the ongoing work.
