I was on a tour with 5 other people when this monkey ran right up to one of the guys who was holding a water bottle, climbed up his leg and snatched it right out of his hand. He then proceeded to use his teeth to twist the cap off. I just kept wondering how did he figure out this was a bottle that would quench his thirst?? Knew to take the cap off…etc. etc….keen observers of human behavior?
