I keep seeing these stories online: "Mygrandparent died and I got more/less money than my relative and now there's hard feelings". I don't get it. If I go first, my wife gets everything and will have to decide what to do with it. My kids (her stepkids for over 15 years now) have a great relationship with her and I'm not worried about that, but my grandkids? They'll get whatever is left after my wife, and then their parents, get what they want. I've never received anything after the death of a grandparent and I couldn't care less.
My buddy had a roller coaster of a time: his folks divorced when he was in grade school, dad remarries. 30 some odd years later, dad is in poor health. Friend's relationship with his step-mom is not great, she straight up tells him that when his dad dies, he can go pound sand and he's not getting shit. She and her kids will get everything. Plot twist: a few months later, step-mom drops dead. His dad died about a year or so later. My friend got everything; the family land, the house, the massive gun collection, the cars. Step-sibs got jack shit.
