I feel like I should but also does it really matter?
I have a friendship group through a hobby. We're quite an eclectic group with the hobby being the only thing most of us have in common. Very different social, edclucational and financial backgrounds.
There's a man I'm not especially close to but who is at most events and more recently has started organising some things. All good. He's nice enough, but is perhaps your typical middle class middle aged man with a touch of unconscious misogyny. I think he means well, but he'll mansplain when he thinks he's being helpful for example.
Anyway, imagine my name is Jane (it's not but another 4 letter name that's never shortened) He's started calling me Janie. No one has ever done that in my 50 odd years.
I don't mind as such, but it's not my name and I always address people by the name they introduced themselves by. E.g. I wouldn't call James Jim unless he told me that's what he goes by.
Does it matter?
