Last Wednesday Dinner

Last night was our last Wednesday meal before B leaves for college and I made him his favorite meal, baked macaroni and cheese.  However, the entire evening was overshadowed by J's incredibly poor decision to trade my boat for 1984 Trans Am.  J and I had been discussing this possible trade (he has been trying to sell my old boat for me) and I had last told him to send me info on the Trans Am including pictures.  He did not respond,  but he had told me that he would bring it to a mechanic friend of mine to check over.  When I pulled into my driveway, my boat was gone and when I called J, he told me that he had made the trade.  I was furious as I never told him to move forward with the deal, but apparently when I made the comment "Your not storing the car at the house" he took that as a green light to move forward with the transaction.  When he got home, I confronted him about the situation asking " why would  this deal be any different from the previous ones?"  "I have always said that I want to meet the buyer and I would sign the bill of sale."  He seemed genuinely surprised and part of me believes that he thought he had acted properly.  It was a tough night for everyone because he was very proud about getting his "first car".  Overall it is a good deal, just a crappy execution.  I plan to pull the engine out of the car and put it into the jeep as the Trans Am needs way more work than it is worth.  He thought he would just make payments to me for the car but I really do not want to deal with that hassle.  He never follows through with financial commitments and it  would  be another divisive issue between us.
