Lookalikes? Not to Their Owners
Supposedly, marine biologists can distinguish amongst very similar-looking dophins, whales, and walruses by their distinctive markings.
In the same way, I can identify my family’s slate gray minivan — in a sea of near-identical gray minivans — by its distinctive pattern of dings and scuffs.
Exception: Newborns
The principle even applies to new minivans, every 4 (or 8) years you get one: then, the car is recognizable by its absence of identifying markers.
P.S.: Ahh, but when you open the minivan doors, THAT’s when they all start to really look alike: a hermetically-sealed, portable pod of old wrappers, empty juice boxes, sun hats, etc.
