Born at this point in Pisces season
Born on March 18, late in the Pisces season, this person stands near the threshold where one sign hands over to the next. Their feelings run wide and their attention keeps drifting ahead toward what comes after. Friends notice them sitting with an ending for a while before they are ready to start again. Being born at the edge of a season teaches a person to hold two moods at once, and that balance can feel both tender and tiring.
