Americans generally consider themselves to be frank, open, and direct in their dealings with other people. They will often speak openly and directly to others about things they dislike. They will try to do so in a manner they call "constructive," that is, a manner which the other person will not find offensive or unacceptable. If they do not speak openly about what is on their minds, they will often convey their reactions in nonverbal ways (without words, through facial expressions, body positions, and gestures). Americans are not taught that they should mask their emotional responses. Their words, the tone of their voices, or their facial expressions will usually reveal when they are feeling angry, unhappy, confused, or happy and content. They do not think it is improper to display these feelings, at least within the limits.
Americans are generally more direct and open than most people from many other countries. They will not try to mask their emotions. They are much less concerned with avoiding embarrassment to themselves or others than most cultures are. To Americans, being "honest" is usually more important than preserving harmony in interpersonal relationships.
