The British vice is overthinking before we speak, which is really annoying. I love the way that, in America, people are more straightforward. The American vice would be sometimes speaking too loudly. You can always hear American people on the trains!

I cry at the end of every episode of "Girls." I'm just so overwhelmed by the truthfulness with which [Lena Dunham] conveys human nature.
