We've been married 49 years and we have learned to work together. But only one is the supervisor. He helps me with my projects but has to do it my way. I help him with his projects and do it his way. We don't do things the same but I often take his advice and he sometimes takes mine. My dad and DGF were carpenters so I grew up swinging a hammer. The only thing DH did with a hammer was hit a stubborn bolt on a piece of machinery. He was a great mechanic but not a builder. He has learned a lot and is pretty good help now.
