I’d been traveling in Asia long enough to know that monkeys there are nothing like their trombone-playing, tambourine-banging cousins I’d seen on TV as a kid. Free-living Asian primates possess a characteristic I found shocking and confusing the first time I saw it: self-respect. If you make the mistake of holding the gaze of a street monkey in India, Nepal, or Malaysia, you’ll find you’re facing a belligerently intelligent creature whose expression says, with a Robert DeNiro–like scowl, “What the hell are you looking at? You wanna piece of me?” Forget about putting one of these guys in a little red vest.
