I have been negotiating a business contract with someone. I had my attorney write edits in a red lined version of the contract. The person I was negotiating with read that contract and believed that I was asking for about 2 times the money I thought I was actually asking for. We communicated back and forth via email while letting this miscommunication grow. He was thinking WTF. And I couldn't understand why he cared about the point. It never really became a major issue because we met for drinks last night and understood the miscommunication. That said, it reminded me of the danger of miscommunications while negotiating. Very hazardous. It's worthwhile to make sure that both parties are talking and understanding the same thing!
