How Do We Cry When We're in a Crying State?

Odds are you're a crier. Why do we cry? Well, let's start with the more obvious cases of crying. And from an evolutionary perspective, why would human beings have evolved this unique capacity? The most empathic thing is in the sense that when you see somebody else who's got distress and they might be crying, in fact it may be your back response to them. Some psychologists conjecture that when we see someone on a plane or watching a movie rolling their cheeks down our empathy for them increases.
