"One death reminds us of all death."
I heard this statement one day no too long ago when flipping tv channels. I don't even know if I have the exact wording correct, but the way I remember it above makes so much sense to me.
Maybe the quote seems simple, like stating the obvious to some people, I don't know.
For me, it allows an understanding of some of the emotions that I've felt in the past few years (and even before that) that I could not make sense of. It gives me permission to feel whatever emotion a new death evokes, as these emotions are from unresolved grief that still needs attention somewhere deep within.
