Some Americans like to think that their society is free of class distinctions. Of course that's untrue. In fact, you can often determine somebody's class from the first thing that they say to you. Imagine for instance that you're at a party and you catch a man staring at your breasts. How he handles the situation will immediately give away his class:
Working class: Nice tits. Can I get you a beer?
Middle class: Nice blouse. Can I get you a martini?
Upper class: Nice tits. Who's your surgeon?
