learning the language of a country isn't enough.if you want to have a pleasant visit,find out as much as possible about the manners and customs of your host country.you will probably be surprised just how different htey can be from your own.a visitor to lndia would do well to remember that people there consider it impolite to use the left hand for passing food at table.the left hand is supposed to be used for washing yourself.also in india,you might see a man shaking his head at another to show that he doesn't agree.but in many parts of india a shake of the head means agreement.ondding your head when you are given a drink in bulgaria will most probably leave you thirsty
