I call all all the women in church sister first name. I feel kinda weird if I just call them by thier name, like I think that they think I'm trying to pick up on them or something, lol. (I'm 46 and single).
My pastor I just use pastor.
Older men I use elder last name or brother first or last name.
When I first meet people in church I use bro or sister.
I use first names for young adults, teens and kids, but they call me brother Mike.
When I become close friends with a male I call them by first name or just plain brother
I feel goofy if someone introduces me as brother ... to someone that is not in church
When I am asking about someone or referring to someone I use brother or sister so and so. " It's sister so and so's birthday today"
This is all stuff I developed on my own.
There's more but I gotta jet outta here.
