coincidence

A coincidence is a striking concurrence of events or circumstances that appear related but usually have no direct causal link. It happens when separate happenings line up in ways that seem meaningful or surprising, often making people feel the moment was unlikely.

For example, imagine thinking about someone you haven't heard from in years, and then receiving a call from them soon after. That is a coincidence because the events are close in time, but neither event causes the other. In daily life, this can also be as small as finding a twenty-dollar bill in your coat pocket and then needing exactly twenty dollars for a purchase.

In larger examples, two people might independently reach the same idea at almost the same time, or two strangers may notice shared details in their lives that feel oddly connected. These moments can spark curiosity and “what are the odds?” conversations.

The idea of coincidence appears often in stories and films too. Writers use it as a plot device to join timelines, create surprise, or build tension. In real life, though, it is usually best to remember that patterns are common in a large and random world, and what feels remarkable may simply be one of life’s random alignments.
