Do people in your country hug in the street? In some countries, it is common for people to show affection(亲密) in public places. In the United States, for example, we often see couples hold hands, hug and kiss on the street, in the park, in the restaurant and even on trains and buses. But in some other countries, people never show affection in public places because their customs don’t permit this, for example, in Korea and China. So, when Korean and Chinese people visit the United States, they sometimes feel very surprised when they see Americans hug and kiss on the street. In some countries, friends show physical affection to each other. In some South American countries, female friends walk arm in arm when they walk along the street together. In Italy and Russia, male friends often kiss each other on both cheeks when they greet. In most countries, men don’t kiss or hug when they greet each other. They usually shake hands or pat each other on the back. People around the world are different in the amount, manner and situation in which they touch each other. 67.
