You're making a lot of generalizations here. What makes you think it isn't offensive to put your feet up in American culture? It depends on the setting, really

You're making a lot of generalizations here. What makes you think it isn't offensive to put your feet up in American culture? It depends on the setting, really. While it may not be offensive if you're just hanging out at home with some friends, it's obviously unprofessional and rude to do it in a business meeting, an interview, at class, etc. You're telling me that your mother never told you to get your feet off the furniture?
