Emotion.
Whatever brain chemistry or osmotic chemical flow that produces it....is sometimes a matter of 'personality'.
I had a guy once, question my personal sadness upon the death of a good friend.
My own distinct ' personality'....made me promise him that upon "his" death..."I will not shed a tear! "
Death is a funny thing sometimes. It conjures some of the most unlikely behaviors and responses...beyond those of solemn remorse and reflection. To some, it is a time to "get it all out".
The underlying contempt.The seething subdued anger or jealousy. The things you always wanted to say but could not....... until meeting at Death's door somehow allowed you a chance to unleash...really...the most unlikely of responses.
And then, enter the vultures. Greedy loveless claws grasping for deaths booty, as their loved one watches from the heavens in somber disbelief?
Still, I am proud to be human... (elrok: "What Doesn't Kill You" )
