A long time ago, I was talking to some of my closest friends after they had traveled abroad. They had just recently come back to the United States and shared a small story of culture shock. The punch line?
"I had never realized how much Americans like to should you to death."
Now, whether this is actually a property of American culture—or perhaps a property of the company we keep—is not a point I wish to belabor. The point is that, as humans, we love to talk about what other people should be doing.
