When you don't know the language, you can be tempted to use hand gestures to get your meaning across to someone while on vacation. Be careful if you do.
Even the most innocent hand gestures can be misunderstood when traveling to new countries. What may seem common to you, doesn't necessarily have the same universal meaning.
The "thumbs up" gesture that is seen so often in North America, as a positive sign is quite rude in the Middle East, parts of South America and Asia. It has a similar meaning to the "middle finger" here in North America.
