True, which is why I prefaced about the nitpick

Not even joking, I use this nickname for her frequently.

Only nitpicking this because I have a family member named Millie. If you shorten Mildred, it would be Milly with a “y”

Millie spelled like this isn’t short for anything, it’s the full name.

This might be the only actual old person trait in this thread (OP included). The rest is basically just “I don’t want to be fucked over.”
