Syag, look at what a “metaphor” is. I am just thinking for myself.
As an analogy, I was driving on a road where my car was kicking stones to the side, and there is a sidewalk below the highway that I can not see. So, I don’t know whether I killed anyone, but newspapers say that there are people killed by those stones every day, and I can compute probability of my stones killing someone. I would not be able to sleep at night, or continue driving that road, or say “funny, I do not know anyone hit”. And if other people can, I do not understand why.
