I Gerrard , I had the opportunity to go to Thailand in the summer. The first day I met with my friends greeting friends with a handshake and a hug . This is normal for me. But the Thailand he was surprised that I did so . I wonder why the teacher asked a friend to do so shocked when I say hello. Professor says The greeting of the Americas will be a handshake or hug, kiss for the display , which is typical of him, but the greeting of Thailand will raise their hands to say hello and respect . So greetings America may be viewed as disrespectful to Thailand .
