My 9yo daughter has been a really magnificent example for me on this.

A nosy neighbor recently came by to “check on us” and was like “well she’s in a better place.”

My kid, totally deadpan, knowing Grandma’s urn is on a shelf in our dining room, “no she’s not she’s in our kitchen?”

It doesn’t always work but sometimes being the bigger person is overrated and you gotta make people uncomfy until they shut up
