I cannot speak for everyone just myself but the death of someone only hurts if you loved them or had some type of feeling for them.
I had people that I knew as well as family members who had died and I was not emotionally affected one bit.
However, when it came to someone I genuinely loved the pain and bereavement was deep.
I am in no way divulging this information to be cruel or inconsiderate. I am just stating a logical fact that the more you loved someone who died the worse the heartache is that one will go through.
On the contrary, when there is no love, care, or a neutral attitude towards someone who passes away there will or may be no regard at all.
