I think everyone grieves in their own way & with their own family traditions or religious values in mind.
I like to remember the dead on the day they were born where some grieve on the day they died. I’d rather think & celebrate their birth & time on this planet.

For me, I think the realization of death is constantly buried & saved for the people who we think are very old. We don’t contemplate our own death or become comfortable with it. We put it off & ignore it.

I like to think of death every day. It walks with me ever day & is always present. It has become a comfort & part of my reality. Some would feel this way about their religion too.

But if death is remembered & not looming in the distance as something terrible, it brings me humility, contemplation & some contentment, plus helps me keep my goals realistic.
But that’s just me lol.
