By definition, an accident is something unintended and unexpected, an innocent mistake. In hindsight, so simple to avoid, but in the moment just before it happens, not even on the radar. I worry about accidents, but never about the right one. An accident is something that occurs when you're not worried.
I had a little accident the other day. So minor that I can afford to make fun of myself about it. A dumb mistake, but also a cautionary tale.
