I hope I won't be giving too much away if I say:

I've met them. Talked to them. They're even more beautiful in person than they are in their pictures.

And totally un-self-conscious. No swelled heads. No "I'm important and you're not" posturing. Just two really neat kids. Emphasis on kids! The Dad's a nice guy too, but he's not even close to being in the same league as his offspring!

By the way, does anybody know for sure how to pronounce the older one's name? I forgot to ask.
