The mistakes will happen, I am glad you gave youself the 2x4 if you have an extra one come over and give me one. I got pummeled today by a few vets. They were right. I don't know if you have read my sitch but you and I are in a very similar place. Your W is 2000 miles away mine is 1500 miles away. Believe it or not you are in a better place than i am. Mine already filed.
However I do go through the 2 or 3 hours of conversation with W one time we spoke for 5.5 hours. It was great.
My point is don't worry too much about the mistakes you make along the way they will happen. I will keep up with your sicth and you should check out mine. I post full conversations you might pick up some tips on how and how not to DB.
