Bad loser?

When I was growing up I was a fan of our local premiership football team and dad often took us to the games on a Saturday afternoon. Since moving in with the wife my allegiances have shifted to her team. This afternoon the two teams are playing each other and we have tickets. My problem is who to support? I'm thinking I'll decide at half time based on the first half performance. Or sooner depending on the size of the Black Cat fans surrounding me. Last time they played up here we also went and my old team lost, much to the delight of the wife and her family!
