Bea, Your responses are very good. They are point on and yet, quite witty. He may not have responded to your latest missive, but he will. He has to think about it for a bit. Also, keep in mind, you are communicating w/him and he's going to keep that going. He knew exactly what he was doing when he advised you that you owed him $38. He wants communication w/you no matter if it's positive or negative. Trust me, he's in second heaven w/your missives. They are clever souls even though they are a little nutty.
I do hope everything went well w/your son and his father. I guess you'll hear about it soon.
Enjoy your weekend.
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.
