In different cultures around the world, eye contact, handshakes, and greetings carry different meanings and social norms. In the U.S. and Canada, intermittent eye contact conveys interest, while in Middle Eastern cultures intense eye contact between genders indicates trust but is inappropriate between opposite genders. Handshakes also vary significantly across cultures in duration, hand placement, and appropriateness between genders. Greetings like bowing, kissing cheeks, or simple introductions are common depending on the specific culture. Touching and gestures that are acceptable in one culture may be offensive in others, so it is best to observe local customs.
