Well, the postman explains, this morning when mail from Japan resumed, a person in Japan went to the post office to drop it off. The letter was taken to Narita airport and placed on a plane which flies to the US, taking around 14hrs, where the letter was dropped off and taken to a mail sorting facility where it was then dispatched to its labelled address, and should arrive here sometime tomorrow or the day after that.

A little confused, you ask: Do you mean this letter I'm now holding in my hand will arrive tomorrow? Oh no, the postman explains. I was telling you about a completely different letter that hasn't arrived yet. Okay, so how did this letter get here, you ask. The postman looks away guiltily and shuffles his feet. What do you mean, he says, I just told you.

Please tell me what is wrong with the postman's explanation. I'm sure you can figure it out. Don't respond with anything about light or vision. Stick to the story.

This story is not a good analogy because in this model there is nothing in the letter (in that particular photon) that is different from the next letter. Once again, you have made an assumption that the photon itself is traveling with a particular wavelength and is bringing this to the eye rather than trying to understand that the wavelength is revealing the object. If the object changes color, the wavelength will reveal this change instantly in the efferent account.
