Your interactions with a certain person are usually quite light, easy, and optimistic. Today, Sagittarius, communicating with this person could be a bit trickier. You may want to settle something or figure out an arrangement or an agreement, but if it isn't going well, don't push it. Wait for a time when things can get back to normal so that you can engage with this person in your usual, easygoing way. Be patient. Try again later - when both of you are in a better mood and there is a better chance of things working out. It will be much better to tackle this when the mood is right.
