    A while back I caught a news report on something called ―couch surfing and the network of trusting souls who make this phenomenon possible. They offer to put up travelers free of charge and help them on their ways. At first, it sounded unbelievable. I mean, inviting strangers into one’s home for one or two nights? Give me a break.

However, I was intrigued. I decided to find it out. The only way to truly learn about this phenomenon was to dive in. So I planned a trip to Finland, a country I’ve always wanted to explore. I would couch surf at every stop there.

If ever any anxiety existed when stepping into the unknown, it disappeared when my first host met me at the train station. Ari looked like my idea of a typical Finn: tall and blue-eyed. Finns were also supposed to be famously reserved (寡言少语的). Ari was anything but. He was a live wire, giving me a warm welcome and walking with me to his apartment, where he showed me the sleeper sofa, served me tea, and engaged me in warm conversations. He also handed me a key to come and go as I pleased.

If this was what couch surfing was all about—trust and friendship—then I had gotten off to a good start. As I boarded my next train to continue my journey, I began to think about this couch-surfing idea. What encouraged these people to open their homes to strangers? I concluded that there was a desire to lend a hand to like-minded folks who might enrich their own lives.

Seven cities in 14 days. Seven hosts. Seven new friends. If couch surfing taught me anything, it’s this: Most people are good and generous. Where will couch surfing take me next? Who knows? But I can’t wait to find out.
