Here’s a picture of the furniture my grandparents left me:
My grandparents didn’t even update their will when my sister and I were born.
Neither did my grandparents. Likewise, my parents didn’t update their will when my children and nieces were born.
The attitude among all generations has been: your own kids inherit, and they distribute to their kids as they see fit.
I wasn’t in my grandparents wills, but I ended up with some of their furniture.
