Born at this point in Libra season
Born in the early stretch of Libra, this person meets the scales before the weights have settled. Picture a friend handed two job offers on the same afternoon, who asks three people for advice before lunch and still has not chosen by dinner. To them the weighing feels like honesty. Fairness matters, but so does the moment they pick a side and stand by it.
