In the deep south my best friend had a party line until early/mid 80’s.
We’d do the teenage girl chat for hours thing but eventually the little old lady who shared the line would get on and say ‘you girls have talked about boys, your makeup, hair, and the other girls enough. I have to call my sister so you need to hang up now’.
LOL.
Party lines are very old school. I don’t know the number of rings provided, I would guess 4 max.
