When Americans are talking, they expect others to respond to what they are saying. To Americans, polite conversationalists empathize by displaying expressions of excitement or disgust, shock or sadness. People with a "poker face", whose emotions are hidden by a deadpan expression, are looked upon with suspicion. Americans also indicate their attentiveness in a conversation by raising their eyebrows, nodding, smiling politely and maintaining good eye contact. Whereas some cultures view direct eye contact as impolite or threatening, Americans see it as a sign of genuineness and honesty. If a person doesn't look at you in the eye, American might say, you should question his motives—or assume that he doesn't like you. Yet with all the concern for eye contact, Americans still consider staring—especially at strangers—to be rude.
