Finding common ground can be difficult when loved ones love opposing football teams.

<a href=mailto:erin.cofiell@nbc33tv.com> NBC 33's Erin Cofiell</a> found one couple who's mastered the healthy balance.

He is a New Orleans Native that grew up liking Tulane and graduated from Alabama.

She is a Saint Amant native who's tailgated in the same spot at LSU her entire life.

Together, they live in a divided house.

Once upon a time, nearly four years ago, Sister Dupont married Neill O'connell. It was a storybook relationship, friends for years, had everything in common, that is, except their favorite football team.

It was a difference they knew about all along..

"I was always aware of it but I remember thinking like hmm, okay, this could be a problem maybe not, but okay," said Sister.

Now, several years and a baby girl later, they're still going strong.

"I married the man, not the university and I couldn't have picked a better man to marry," said Sister.

Licensed clinical social worker Bill Calkins said that when it comes to relationships, difference in opinion is often a good thing.

"When a couple has everything in common, it can get boring. So absolutely a little healthy banter is good, when it starts to get mean, it's a problem," said Calkins.

For example, when couples are very critical, call each other names, and argue, because of their sport teams.

"If you find yourself doing those kinds of things... you know you are somewhat out balancing your passion for your sports team for you passion for your loved one," said Calkins.

He said its all about compromise.

"Sometimes you need to agree to disagree," said Calkins.

And that's something Sister and Neill have a firm handle on, from sharing TV time, to rooting on the other's favorite team.

"We're not so crazy that when we go to each others home stadiums we wont put on a piece of flair for the other ones home team or whatever, i'm happy to do it,

Both admit there are instances where they've argued over their teams, over who's fans have more class.

"Other than that, the only time we've sort of quarreled is the last time that Alabama beat us, what was that hunny? 5 years ago?" said Sister.

But it's mostly just playful banter.

"Ultimately do we go to bed saying 'Tiger Bait,' 'Roll Tide,' no, it's not that big of a deal," said Neill.

As for the baby, well, she's a Tiger fan.

"She doesn't look good in red," said Sister.

And when she and any future siblings start looking at colleges, it'll be their choice.

"They'll go to school wherever they want to go to school, so long as its not Auburn," said Neill.

And they'll all live happily ever after.

Despite the close game in Tuscaloosa, LSU came out on top. The victory gives Sister another year to rub it in.
