The way we dress is important. Most countries are now used to tourists and it certainly isn't necessary to don a sari in India or a yashmak in Tunisia. But wherever you are, it's better not to offend the locals by strolling through the streets in just a pair of shorts or a bikini, unless it's clearly accepted by everyone. Be aware that sometimes offence can lead to anger and even assault.

Food is another area that can cause problems. Many countries, particularly those in the Far East, enjoy a different kind of cuisine. For example, they may eat meat that we consider highly inappropriate or offensive. When visiting such a country it is important to remember that you are their guest and should not offend anyone for doing something they regard as perfectly normal.

There are also differences with gestures and body language. Giving the thumbs up in Saudi Arabia won't go down too well, no matter how pleased you are with someone - it's pretty much like giving someone two fingers over here. Pointing used to be thought of as rude in Britain and still is in many countries, especially with the index finger. And things can get very confusing if you nod your head at people in Greece, Turkey or Bulgaria, as to some this actually means no.

Did you know?

Another important tip is to learn some of the local language, even if it's just a few sentences from a phrase book. Showing that you've made some effort can go a long way towards better relations with people overseas. Think how you might react if someone from another country was pointing and shouting at you in a language you didn't understand. Most people, regardless of which country they are from, are normally friendly and welcoming as long as they're given the right signals.

Do some research before you go, learn some phrases and enjoy the differences when you get there, and if you cannot travel without causing conflict, don't go.
