Stumbling on something unexpected is one of the great joys of living in a city — heck, of living anywhere near other people. It starts raining, you duck into a restaurant, and it becomes your new favourite place to eat. You stumble into a concert in a park, and it becomes a highlight of your summer. It's not that all accidents are happy, or that all surprises are good, but we don't know how something will affect us until after we've experienced it.
