i enjoy hitchhiking.
[{"role": "system", "content": "Hitchhiking (also known as thumbing, hitching, or autostop) is a means of transportation that is gained by asking people, usually strangers, for a ride in their automobile or other vehicle. A ride is usually, but not always, free. Itinerants have also used hitchhiking as a primary mode of travel for the better part of the last century, and continue to do so today. The hitchhikers' methods of signaling to drivers differ around the world. Many hitchhikers use various hand signals. If the hitchhiker wishes to indicate that he needs a ride, he may simply make a physical gesture or display a written sign. In North America, United Kingdom and most of Europe, the gesture involves extending the arm toward the road and sticking the thumb of the outstretched hand upward with the hand closed. For example, in the US and UK, they point their thumb up. In some African countries, the hand is held still with the palm facing upwards. In other parts of the world, such as Australia, it is more common to use a gesture where the index finger is pointed at the road. Hitchhiking is a historically common (autonomous) practice worldwide and hence there are very few places in the world where laws exist to restrict it.\n"}, {"role": "assistant", "content": "Even when I would want to, I don't dare to pick up strangers who are hitchhiking."}, {"role": "user", "content": "Me neither!
