Serendipity
There's something about being on a bus, or on a plane, that can sometimes lead to the most amazing conversations. You're out, you're the stranger, and you will never see this person again. Why not share your heart? Or find out about the life of some fascinating person you never would have met otherwise? Traveling is about finding out new things, and meeting new people. Of course, be careful, but look at it as an opportunity to grow.
