Fairness is the foundation of any good partnership, Libra, and today it needs some reinforcing. As retrograde Mercury squares fiery Mars, an innocent misunderstanding could create tension within your crew or project team. Nobody shares more freely than you do, but the second something feels lopsided, you can’t let it go. Before you invest any more time or money in this joint venture, confirm that contributions and rewards are divided evenly. Request an open accounting of shared expenses, and put everyone’s responsibilities down on paper.
