You're the stereotypical Canadian in the world's eye - apologizing for winning. It's ok to be happy and proud, bud.
Do you actually think that American fans would be feeling the way you seem to if the circumstances/score had been reversed? Not a chance - and I wouldn't blame them one bit for it. If the Americans win tomorrow, which I think many (including) Canadian fans, are expecting them to, look out. They will collectively be rubbing it in infinitely more than our select few have been. And, again, I won't be blaming them as I consider it nothing more than the spoils of victory combined with national pride, which is nothing to be ashamed of, imho.
