I once met my school mate (we both graduated just a month prior) in a picnic spot. I was talking to her a little away from our families. One money came sat closeby and started masturbating. We were not open and close enough to acknowledge what was happening and move away. Instead, we were pretending not to notice what is happening. We managed to finish our conversation while the monkey finished its business. I was embarrassed but didn't reveal. In fact, until today I never even mentioned this to anyone. I had also seen monkeys harassing usually the weaker and vulnerable people, robbing/stealing houses. I do not like monkeys near human settlements. They are too intelligent, clever and bold to be near humans, especially children. side note: couple of years later I learnt she became a monk. While this might sound funny to some, I was taken back. She was one of the most gorgeous girls I ever saw and came from affluent family in that area.
