My grandmother had this quirk where she'd start reaching for names of people she knew because she just couldn't remember your name right then. I like to think her brain was buffering.

They'd usually be in the vicinity of each other, like my brother or father's name, but sometimes she'd be way out there with a cousin or the neighbour.

I tell you though, it didn't feel great when she looked right at me and called me by the family dogs' names before she got to mine lol
