Who is this stranger living in my house?

My child speaks with a British accent ... almost. She says things like, "STRAW-brees," and, "shopping trolley," and, "lift." She inflects her voice like a Brit, which luckily is much like an eastern North Carolina accent anyway, but even that is frightening. Mark and I have both managed to come away practically unscathed, accent-wise, from our periods of time both in the south and the northeast. Not that I mind having a Texas accent when I speak with my mother, but I'm just pointing out fact. Still, who is this child? Will it go away when we return to the U.S.?

And will I start speaking like a normal person as well? I've just begun training myself to say, "It's meant to ..." rather than, "It's supposed to ..." and I'll probably sound like such a freak saying such phrases upon immigration to America. That's another thing: calling it "America," as most Americans do, rather than "the U.S." or "the States." Jeezy Creezy. For all my cultural longing, there is going to be a lot of culture shock upon returning to American soil ... assuming that's where we're going this summer.
