All 5 of my grandparents lived in the Midwest while I grew up in New Jersey, so my brother and I only saw them twice a year at most. I have positive memories of all of them, but I would only say I was actively close to my maternal grandmother and my paternal step-grandmother, since those are the two who I got to know as an adult. I feel like this is not uncommon!

I inherited precisely NOTHING from any of my great-aunts and great-uncles, and wasn't expecting anything either. I also inherited nothing from my grandparents except a moderate bequest from my step-grandmother, because they willed everything to their kids, not their grandkids. Is willing stuff directly to one's grandchildren a common expectation these days?
