I have a relatively common name for my area. Let's say it's James and that I do not go by Jim at all.
When I introduce myself as James, some people immediately say "Hi Jim! Nice to meet you!".
Why?
I don't understand it. I am not mumbling or saying it unclearly. I would never say "Hi Mike! To someone who just introduced themselves as Michael. I would use the name they just gave me.
I'm not mad about this. It's rare for me to get pushback when I correct someone, so it isn't a big deal. But it happens pretty regularly, and even seems to be getting more common for some reason. I must be missing something. What am I missing? Does this happen to other people too?
