Grandmothers picking what they want to be called...

Tammy 💜👼🏼

Vent sesh... so my mother in law wants to be called Nana but I hate that...🙄 I grew up in foster homes and a girl I lived with had that nickname and it’s one of those names that just haunt you and idk how to tell her... any suggestions? Should I stop being a bitch and just roll with it?
