What do you do when you don't enjoy the same activity that your partner loves?

[specialmom]

This has always been a dilemma for me.  I TRY.  But deep down, I do not enjoy some of the things my husband likes and he doesn't love some of the things that I do either.  It's basketball tournament time.  My husband thinks that the NCAA tournament should be national holidays.  He used to take the days off of work, no joke.  He gets his whole bracket thing going and pins it on our wall!  I have a team or two that I say to myself "nice if they win" but truthfully, I really couldn't care less.  I get my fill of sports from watching my kids play them.  My husband will park it in front of the tv and preferably in front of 5 tvs to watch every bloody game on and shouts at the tv, gets all excited or mad, paces around when things are going bad for either his teams he's in love with (and he IS in love with them) or his picks in the pool he's participating in and he's going to drop lower in the pool rankings and won't win . . .  I mean, it's hard for me to watch.  And my eyes are rolling into the back of my head because I'm so bored.  

Am I alone here?  

what do you guys do when you have NO interest in one of your partner's passions?
