For the most part, reporters will arrive at the scene of a given story after its events have already taken place. Sometimes they can arrive early enough that the matter is still ongoing or be on hand during a developing situation, but the job involves a lot of piecing information together after the fact.
Sometimes, however, circumstances can have it that journalists are not only there right as their stories are brewing, but actually find themselves becoming part of them. This has often happened as a result of working from home as the mishaps going on around them become funny anecdotes in their own right.
But whether the results are funny or simply amazing as in the case of one Boston reporter's chance encounter, it's clear that this phenomenon is just as possible when they're out in the world.
