Well, all we know yet is that Chris will make his vow in his own language.the language issue bugs me, too.

This doesn't necessarily mean that he will not make any effort to learn the language or say a little bit in Swedish at some point during the wedding, perhaps during his speech. Let's wait and see. Why are people always so quick in critizising?
