"I would be hurt too if I had spent years "filling in" for a deceased grandparent and never being acknowledged."
OK, I feel like a broken record, but why is being called "grandma" seen to be the mark of being acknowledged? What about the time spent together, the hugs and kisses, the "thank yous" and "I love yous"? Isn't that what matters? If those things are there, does being called Beatrice instead of Grandma really undermine them or make them less meaningful? Why should an adult potentially sacrifice the relationship by putting the grandchild into such an awkward position if she has the stuff that really matters?
If those things aren't there, isn't that the real problem and not the label? Why would I call someone who I have no attachment or relationship to by a special name, especially if it will hurt people who I do have relationships with?
I get it that names are important to people; I really do. My point though is that maybe in a time where family relationships are so complicated we should question that, and focus on the relationships instead. We should all question why it matters so much to us, why we would let it become a source of tension and anger in our family.
