Wonderful post.
When I find myself in a big city, if there is an old cemetery there, I must visit it. the peace and silence that reigns there brings a certain tranquility to man...
We Orthodox do not celebrate the "Day of the Dead" on the first of November as you do.
We have "memorial days", which we mark four times, in February (winter), June (summer), October and November (autumn), when we go out to cemeteries and visit the graves of our loved ones.
Judging by the dates in the year 2000 when your grandmother and grandfather passed away, I would say that the grandmother passed away from grief over the death of her grandfather, with whom she spent almost her entire life?
As well as from my friend, a ninety-something-year-old grandmother who passed away, and after three months and a grandfather, who kept saying that he couldn't live without her...
Yes, it was more or less like you described it.
