As a species, we are farcically exploitable but this is not Natural. We've been conditioned with corrupted sentiment and sensitised with emotional abuse to the point where we're pathetically, tragically fragile. Our emotional feelings consistently make us faceplant. We don't do ourselves any favours when we get emotional, that's for sure.
I'm substantially less emotional these days but I had an incredibly emotional childhood. My siblings and I were forced to contend with a mother who was hysterical when she wasn't catatonic. I carried residual frustration and bitterness throughout my teenage years and into my late 20s.
The remarkable thing is that I was aware that I more tightly strung than most, but the idea that my feelings were in my control never really occurred to me. It was just the way I felt. How could I help it? People were making me feel that way.
I see a lot of people in a similar position.
