like not the normal kind of dislike, you hate it as if it were a person

Chimps are much admired for their tool use and for their problem-solving relationship with things as they find them...the orang is, let us say, not so replete with enterprise. Give an orangutan the hexagonal peg and the several shapes of hole, and then hide behind the two-way mirror and watch how he engages with the problem.

And watch and watch and watch--because he does not engage with the problem. He uses the peg to scratch his back, has a look-see at his right wrist, makes a half-hearted and soon abandoned attempt to use his fur as a macramé project, stares dreamily out the window if there is one and at nothing in particular if not, and the sun begins to set. (The sun will also set if you are observing a chimp, but the chimp is more amusing, so you are less likely to mark the moment in your notes. An orang observer has plenty of time to be a student of the vanities of sunset.)

You watch, and the orang dreams...when casually and as if thinking of something else, the orang slips the hexagonal peg into the hexagonal hole. And continues staring off dreamily."
