If you ask me what I think of as “so American,” my brain short-circuits a little bit. Visions of flags, fireworks and all things red, white and blue on the 4th of July immediately pop into my head. But beyond that, I draw a blank. Everything else is pretty universal, as far as I can tell. Well, my friends who live overseas would like a word. They remind me quite how American something like football is. Not soccer—American football, which you don’t actually use your feet for.
