We started calling them bandars in India. One day we were walking down the street in Rishikesh and heard a group of kids screaming "bandar, bandar!" and then realized they were talking about the monkeys.
At Angkor, I got sucked into the monkey feeding racket. There's a highly socialized troupe of monkeys by the side of the road, who have plenty of food to eat due to the tourists feeding them bananas and some other odd fruit that local vendors sell. I couldn't resist this seemingly safe opportunity to have a moment with a baby monkey.
