Why people shed tears at all

One explanation for crying is that it is a social signal. It expresses to someone how you are feeling. Negative tears may be a signal for help. Happy tears may indicate that a person is eager to be close to others and have no mean intent.

How you express happy tears depends on who you are. An extrovert more often will experience beauty tears. Empathetic individuals cry affectionate tears more frequently, and liberal people are prone to shed beauty tears.
