Just because you don't have much in common with someone, or perhaps you don't even like that person, it does not mean you can't come to an agreement that is mutually beneficial. You may be up against someone now that you don't like or respect, and perhaps for very good reasons. However, Sagittarius, there may be an agreement you need to reach in a negotiation, and you can certainly discuss this in a way that will bring you what you need. Overlook the things that make you dislike this person and focus on any mutual goals.
