So, your sister was surprised that I knew immediately that that accidental cremation story was bogus.
It’s not hard to hesitate to believe something that is so far-fetched, in fact, I recommend it. I mean, if someone told you they had destroyed the moon, would you immediately look up to check or would you scoff first and then tell them to prove it? I mean, destroying the moon would be hard, so they should easily be able to handle a little task like proving they did it.
I must admit that I have a tiny edge when it comes to funeral stuff these days. Doing research on how people handle dead bodies is mildly unpleasant and it has a tendency to stay with you, like a sick cat.
It would be impossible for a person who routinely handled dead people to make this mistake. Only the very freshest dead body would resemble a napping coworker. The person moving the body would notice that the body was warm, which would be almost as much of a surprise as recognizing that it was also Steve, their non-dead coworker.
Stay skeptical, kids!!
