That is very disappointing to hear. Of course it sucks to finish third when only two spots are available! No one would disagree with that! Now, if this were the golden age of 6.0 and the "wait your turn" paradigm, maybe Kaitlyn would have some reasonable justification for having her nose out of joint when a "younger" team finished ahead of her and her partner. But it's not that golden age anymore. Now, you have to earn it; it's no longer enough just to "deserve" it because you've been around a long time. Vanessa and Paul earned it; case closed.
Besides, W/P can go to Four Continents and likely do quite well there. Sure, it's not as "exciting" as the Olympics, but it's still an honor to represent your country internationally--and it's also a great way to lay more solid groundwork for yourself when the teams ahead of you retire and you're hoping to be one of the new leading teams. It's all part of a process, and there's a bigger picture. I hope Kaitlyn realizes that throwing a pity party for herself is not going to endear her to fans who value good sportsmanship.
