Be careful about how you approach any business deals today, and try not to let your emotions get the better of you. Someone could try to push your buttons: don't let them. They're bringing up issues to get a rise out of you, not to make any real or valuable points. A well-phrased comment made at the right time will be more effective than any threats they could ever make. Respect other people's arguments, and take note of how each individual behaves in a pinch.
