I've had a lot of people in my environment die, but most of them were people that I didn't know very well or just someone I worked with or whatever. My dad died when I was 19 and if I grieved at all it was for a lifetime of drama that my family had to put up with before he did the decent thing and ate a bullet.
That's the "a lot". I've had a couple - very small number - of friends, two of which could be considered close that died unexpectedly. One was heart condition and his health wasn't great to begin with, so not much of a surprise even though it certainly wasn't planned. The other was tragic - I worked with a girl Sabrina.
I quit the job and moved on, she stayed behind for a few years. She eventually got fired, I think because she wanted to be paid a living wage, and they fired her. While she still had insurance she figured she should get a check-up while looking for a new job and she was diagnosed with TB.
I don't have the details, but shortly after getting the TB meds she went into renal failure...died a few days later. I saw her in the hospital the day before she died and was one of the only white people at her open casket funeral. I didn't care for the corpse.
There have been a few times when I've seen a woman that resembled her and I felt a little saddened by it, but still...not what I would consider grief.
I've lost pets...those always seem to hit harder, but there's still not much in the way of tears.
I'm not sure if I'm broken or practical.
Everyone and everything dies. There are 8 billion people alive right now that in 150 years time will absolutely be dead. Just seems easier to recognize and understand that. Our time here is fleeting. <shrug>
