If he shows up for the meeting, keep your points short and to the point. His concentration level is that of a gnat. They can't handle a lot of talking and begin to tune you out. So, to get your points across, keep each item very short and sweet. Count to ten before you lose your patience and remember, you aren't dealing w/an adult, but a man still on a child's level when it comes to business. If he acts unsure of what you've said, ask him to tell you what he heard from you. Try to keep your voice calm and level and definitely look him in the eyes when you are speaking to him. After the conversation, follow up with a text or email stating what took place and what has now been agreed upon.
I will be thinking of you and hoping you can at least get some answers, if not all of them in this one meeting.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
