In the summer of 2007, a group of international students were attending college in England. They had a long period of time between semesters for travel, so they decided to hitchhike as far as they could in other European countries. In many places, they were successful. They put their thumbs out or pointed them backwards and smiled; friendly drivers stopped. As soon as the first traveler got a “yes” answer from a driver, he motioned with his hand or fingers for his friends to come—or he held both thumbs up in an “OK” sign or made a circle with the thumb and the next finger of one hand. The young tourists saved money, saw a lot of the countryside, and had many interesting conversations and experiences.
However, the international students were not so lucky in Greece and Turkey. Most drivers ignored them; fewdrivers stopped to give them rides. Some drivers shouted terrible words at the travelers; others even got out of theirtrucks and wanted to start a fight. The students felt unwelcome, confused, and afraid. After they traveled back to wherethey were studying they learned that it were their hand gestures that had caused them trouble.
