What's the deal with political correctness

Physical contact: Generally, Americans are not very tactile outside of their families and close to relationships. However cities that are more internationally exposed may adopt more physical contact in their mannerisms. Touching someone of another gender, especially in the workplace, can be misinterpreted.

Personal space- Americans like to be given a fair amount of personal space, so try not to encroach on it during a conversation. If an American feels you are ‘in their face’ too much, they will probably not mention it and simply step back.

Gestures- it is the best to nod or show some kind of sign that you are listening throughout a conversation.

Smiling- Many Americans smile when passing the strangers on the street as a simple gesture of goodwill.[6]
