What Other Standard Things Can You Think of?
From the perspective of the person who sent the first text, it probably made sense to send an image of a “standard cable.” What in the world is a “standard cable,” anyway? Aren’t there, like, a million different kinds of cables? Or is there one cable that represents all cables in existence?
The OP was probably just as confused as us, so, in response, they replied by sending a picture of a “standard cat.” Yeah, this white, gray, and orange cat represents every housecat in existence—pretty much the same way the standard cable is a universal representation of every cable you can think of.
