No 2 X 4's coming from me. That was a beautiful letter you wrote and I think when you're as far along in this as we are, and knowing there is still a long way to go, a message like this won't do any damage and just maybe plant a few seeds. Who knows? The worst has already happened and it's not like it's going to push him out the door.
I'm thinking it may be time to write something similar to my H.
