For the sake of pantomime, I get in character for disliking Cork when we're in the same division, but even that is forced. I can't generate enough interest in any other club to truly hate them. I was pi55ed off with Dundalk for a few years after the '97 playoff.
I surprised myself at how wound up I got against Liverpool in last season's friendly, although I think that was more to do with the local Waterford people shouting against their local club.
