I've been quite lucky in that I was well into adulthood before I had to experience anyone close to me dying.
My friend is ten years older than me and it was amazing to think of having a grandparent at that age too. All mine have long since passed on. Her grandmother was actually born the same year as my maternal grandmother. I never met my maternal grandfather, who was 13 years older than her.
So cool to have family around that long. I buried the only parent I ever knew when I was 37. Grandparents and all that were gonna well before. No siblings, either, I don't many like me.
