A greeting is a friendly expression or gesture used when meeting or welcoming someone. Greetings usually happen before a conversation and sometimes accompanied by some greeting behaviors such as a small kiss or a hug and handshake. Though the time to greet someone is short,      
    . Just as the Chinese saying goes “A kind word could warm one for three winters, a bad attitude would make one cold even in hot summer.”
The following are some greetings in different countries.
1. America: Firm handshakes should last 3-5 seconds.     . When greeting multiple people, make eye contact with the person whose hand you are taking, and then go on to the next. They are not used to standing too closely.
2. United Kingdom: A hand shake is the most common form of greeting for both men and women. When people are already familiar, verbal greetings are used. Personal space is important and people can feel uncomfortable if someone stands too close to them.      .
3. Australia: A handshake is the preferred greeting. When speaking to an Australian, keep an arm’s length distance from the person.      , and eye contact should be maintained as well.
4. Canada: A handshake is traditional. Men usually wait for women to offer theirs. Direct, but not too intense eye contact is acceptable, especially to convey sincerity. The standard distance between two people should be two feet.      .
