Believe it or not, I do understand. My W is the sports junkie in our house. I watch football every four years when the World Cup comes around and can get pretty wrapped up in in that. I also like Formula One racing, which amounts to 18 races per year. She watches baseball, basketball, and hockey, and used to watch football (American football, that is) along with the others - literally hundreds of matches per year. I have no interest in any of those.
I would be over the moon if she would show one tenth the passion for me that she shows for the Dallas Stars hockey team.
