I've always found a weird comfort in how literature talks about strangers bumping into each other. It's not just about meeting someone; it's about the shared, fleeting moment that changes you. There's a line from a Haruki Murakami book, 'Kafka on the Shore,' that nails it: "Sometimes fate is like a small sandstorm that keeps changing directions." It feels like strangers are those little directional shifts. You can't plan for them.
Another one I love is from 'The Alchemist,' even if it's a bit overused. "When you want something, all the universe conspires in helping you to achieve it." The 'universe' part is those chance meetings, the person who gives you the wrong directions that lead you to the right place. It's about trusting the randomness.
My favorite, though, might be from an old poem by W.H. Auden: "Thousands have lived without love, not one without water." It's not directly about strangers, but it makes me think that some encounters are as essential and accidental as finding a well in a desert. They just happen, and you're different afterwards.
