1、Learning the language of a country isn't enough. If you know the manners of your foreign friends, you will probably be surprised just how different they can be from your own.
A visitor to India should remember it is impolite there to use the left hand for passing food at the table. The left hand is for washing yourself. Also in India, you might see a man shaking his head at another to show that he is disagreeing. But in many parts of India a side-to-side movement of the head is to show agreement. In Bulgaria you shake your head to show "yes"—a nod shows "no".
In Europe it is quite usual to cross your legs while sitting and talking to someone, even at an important meeting. But doing this could cause offence to a Thailander. Touching the head of a grown-up is also not done in Thailand.
Knowing about manners is useful when you are traveling, and you also need to know the language used to express the customs.
