"please come back with a british accent"

I realized over the weekend, I have started to adopt a British accent. But only in one word, "sorry." I now say "soh-ree" instead of "SAR-ree". This isn't a noticable accent, the way a fake Beatles or Cockney accent might sound, but there's a softer quality to it. I also think it's very telling that my first word is sorry. Though really, it's somewhat of a defense mechanism; so that when I elbow someone on the Tube, or pass them on the wrong side (left! it's always left now!), they don't shoot "stupid American" glares over their shoulder. Actually, I get mistaken for French more often. (Which is usually followed by "Good, I hate the French!" when I say no. I think they're kidding...)
