Crying is a natural and helpful behavior that allows humans to express emotional pain or frustration. However, if you learn to use crying to manipulate others in childhood, you may continue to use this behavior in adulthood. If your manipulation using tears is successful, you may not develop more mature and adaptive methods of communication. Some people cannot tolerate tears and easily give in, making them easily manipulated when they see negative emotions expressed via crying. It may be related
