You're right, you're right, you're right. And little Hilton will find herself using the language bit as a prestige wedge anyway.
As for the kids not remembering anything, when I pointed this out to my wife, she said, But if you say you took them, even if they don't remember, they're going to ask to see the pictures from the trip.
Easy, I replied: Tell them they were lost in a fire. You know, the one where dad rescued everybody? That's a two-fer: Save the money, become a hero.
On the other hand, there are "memories" I have which have been family stories for so long, it's not clear to me whether the recount of the story is embedded in my brain, or if I remember it myself. So maybe taking a 2-year-old around the world then talking about it til she's 20 is the trick. (hee)
