Born at this point in Libra season
This person was born in the middle of Libra, when the season has moved past first impressions and into the harder work of choosing. Weighing options comes naturally, so a choice can feel like a loss of fairness. At the same time, they want decisions made and settled. A friend asks where to eat, and they can list six good options while feeling pressure to pick one. Wanting harmony and wanting a clear answer share the same afternoon.
