Why do people travel? Answers may vary to this question but one of the most important reasons is to change our routine way of living and to gain new experiences. It is exciting to make new friends during a journey. Sharing the feelings with companions is far more interesting than experiencing the whole trip just by oneself. Also, it is safer and more economical because there is another person to rely on and to share the bills with. More importantly, there would also exist opportunities to meet some local friends who would be perfect guides to help make a trip more complete. We can learn about different cultures from local residents, and their advice would be invaluable to us since they are more familiar with the local environment. Help is always needed during a trip when one is exploring the unknown world.
