Each part of the United States speaks English in a slightly (or extremely) different way than the rest of the country.
What I would like you to do is pay attention to how Californians speak (yourself included, if you believe you talk like a Californian).

Be thoughtful and interesting as you observe; you might mention things in these (or other?)
general categories: Your list (with brief explanations, where apropos)
