 | | Suppose you also notice a dog in that direction, a dog which is sometimes directly between you and the person and sometimes a bit off to one side; but as you observe this person, the dog never strays far from your line of sight, no matter how long you wait and watch. |
 | | You might logically conclude that the dog is with that person, and perhaps even attached to the person by a thin leash which you cannot see from a distance. |
 | | It would seem very strange to conclude instead that the dog is, say, exactly halfway between you and that person, and that some mysterious influence is keeping the three of you more-or-less lined up, so that when the walker moves a long way to the right, so does the dog! |
