We had to be very careful of these chaps in Rajasthan. They are cheeky indeed. They'll steal anything if you put it down, even for a second, and they're pretty aggressive too. Definitely not as cute as they look!
Same in Bali. One jumped on my backpack as I was taking pictures at the cliffs of Uluwatu. Not cool. They were taking peooles glasses, cell phones, etc.
@darylo Yes, I remember a holiday in South Africa. We went to the beach and left the door of our chalet unlocked (at least my husband did ...). Came back to find the monkeys had visited. They trashed the joint and ate everything edible! We learned a lesson there!
