The well-dressed ape, aka Homo sapiens, is an odd mammal. It pals remarkably frequently, and with extraordinary affection. With related enthusiasm, it's going to devour to the purpose of undermining its personal health–behavior unthinkable in wild animals. The human marks its territory with doorways, fences, and plastic flamingos, but if it’s too remoted it turns into depressed.
