All kidding aside, I am blessed with my wife of 34 years that actually pays attention to my many oddball interests. I wouldn't say she takes a keen interest in all of them, but she has made an effort to at least understand my attraction to them. She can talk a good line with regards to all of them, and has more than just a cursory understanding of them. Oh, and we do have one shared interest, that is our "favorite hobby" as well.
