A Primate and a Canid Relating on the Same Plane

What fascinates me is that the primate is relating to the little puppy on the same level, that’s PLAY. They seem to have no prejudice that they might be dangerous to each other, that some day the canine might be a predator to the primate or vice versa. There are stranger bedfellows. But sometimes it’s easier to explain, like when a frog tries to hump a turtle shell. There’s a stronger drive in that, than just PLAY.
