If you can't take your wedding anniversary over something you can fucking DVR and watch a few hours later you have some bigger problems to worry about.
And if you demand that you celebrate on one specific date and at a specific time during which an important event is happening that your spouse enjoys quite a bit, then you've got some problems too.
Yes your wife is more important than a Super Bowl. But your husband and the things he cares about should be more important than a celebration on an arbitrary date. I'm not a big sports fan or anything, but thank god I married someone that's willing to make compromises on stupid shit that some people think is important "just because." We've celebrated countless birthdays, anniversaries, holidays, and stuff on different days, and we're not losing anything at all because of it.
