完形填空

    It was a hot day in Bangkok (曼谷). I was walking out of the busy Grand Palace, and some 1Thai teens started asking me questions. Noticing that I was2, they were interested and wanted to know more.

    “Oh, so lonely!” they said to me when they learned I was,indeed,3 solo for the long journey. I smiled and shrugged. They didn't know I've 4 been alone.

    I'm surprised by how much more outgoing I've become. Instead of putting my5down and ignoring the person who may be6me on the sidewalk, now I smile and say hello.

    The only bad thing is the fleeting (短暂的) nature of the relationship one builds on the7. I've felt sad more than a couple of times over parting ways8a fellow traveler. But there are always9friends and possibilities just the next town over.

    Part of the10of taking this trip was the knowledge that I'd be doing this alone. At first, I tried to get friends to11with me for various legs of the journey. I asked close friends, then even not-so-close12, then slowly realized that I might never travel if I13around for a time when a friend of mine would be free to14me.

    If I was really going to do this, it would have to be alone.

    As it turns out, traveling alone is the best15I could have made. You always have to make16considerations for others when you travel with others. Sometimes, you have to do things you don't feel like doing.

    Solo travel is amazing. And really,17I truly want and seek out18, I am never alone. I always have a group. I never feel19. Sometimes, being alone forces you to reach out to people you might not otherwise have ever 20.

    So don't fear traveling alone. It's the best thing there is.
