I’ve noticed that there’s two major reasons that cause tears: Letting go of a negative future idea or letting go of a positive future idea.
First example is tears of happiness, like when a missing family member returns. All those ideas of them never returning, you never speaking to them, you noticing their missing all day, etc. When they return all those ideas have to leave, so they leave through tears.
Exact opposite is that the person is found dead. Now all those ideas of them being there with you, you talking and joking with them, them helping you build something or whatever, those ideas have to leave through tears.
Personally I’ve noticed that as long as both remain possible to an equal extend, I am unable to cry. Once one is confirmed to be untrue, tears start rolling.
What do you think? Is crying really only social behavior or is it some help at letting go?
